2.3.1 and JS problems?
Tony Graham -
回帖数：17
I am using firefox and if JS is enabled I cannot add activities and rsources. When I turn editing on the add resources link is not enabled.
If I turn JS off then I do get the add respources drop down menus but the layout and working of the site is then broken??
Can anyone help with suggestions or know how to fix this
Thanks

What do you mean by "the add resources link is not enabled"? Do you mean that you don't see the activity chooser "add an activity or resource?"

I mean that the text "add an activity or resource " is shown but this does nothing, you cannot click on it unless javascript is disabled.
Also just noticed that disabling javascript causes all the menu block to disappear?
I'm using the fusion theme.

Hello Tony,
I have the same problems, but until now I don't find a answer.
Do you also have problems with the upload of files?
Kind regards
Sarah

You probably have javascript error. Check the javascript console in your browser.

For file-upload I get the following error:
If I edit a course and want to choose activities I get this two errors:
1) TypeError: M.course.coursebase is undefined
Source:
http://www.xxx.de/moodle/theme/yui_combo.php?moodle/1346920223/course/toolboxes/toolboxes.js
2) Error: extend failed, verify dependencies
Source:
http://www.xxx.de/moodle/theme/yui_combo.php?3.5.1/build/yui/yui-min.js
I think it's a problem between javascript and the server, because with other moodles (like this forum) I have no problems with the file-oplaod or anything else.

I find a solution for the problem.
There are difficulties in the communication between the Moodle and the local JavaScript library YUI.
If you follow the path Site administration -> Appearance -> AJAX and Javascript there is a box "Use online YUI libraries", if you set it to Yes (Default is No) the javascript should work without any problems.

Thank you Sarah
This appears to solve some of my issues.
The main problem now it that moodle refuses to send out emails for registration etc.

I still have not found a solution to this problem, is anyone else experiencing similar difficulties.
If I click the "turn editing on" button or link within a course then the main menus and blocks disappear and also the links which would normally allow you to upload a file add a lesson etc are not live. The drop down box appears but none of the links work.
The error I get is as below??
Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 524288 bytes) in /home/blackcat/public_html/learning/lib/htmlpurifier/HTMLPurifier/DefinitionCache/Serializer.php on line 33

Tony,
this is not a javascript problem - it's caused by lack of memory on php side.
See http://docs.moodle.org/23/en/Errors_FAQ#Fatal_error_allowed_memory_size_exhausted._How_do_I_increase_my_php_memory_limit.3F

Thanks for that, however when I create the .htaccess file and include the line
php_value memory_limit 64M
I get
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, webmaster@blackcatlearning.com and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
The hosting company I use have been pretty useless in helping to sort this out!

Not all shared hosting/remotely hosted solutions are the same. And ditto for supporting Moodle version 2.
If I am correct (by putting together bits and pieces), have determined that you are remotely hosted at WebHosting UK Com. If I am incorrect, then please disclose some more information concerning your hosting setup.
http://kb.webhosting.uk.com/
First article is about how to increase memory usage for PHP for WordPress.
http://kb.webhosting.uk.com/how-to-increase-the-memory-limit-of-php-and-wordpress/
"If your website is hosted on a cPanel hosting account, you will have to talk to the web host for increasing the memory limit. As WordPress comprises of a collection of PHP files, you will also have to increase the memory limit of PHP."
If one has to do that for WordPress, would imagine the same is true of Moodle.
http://kb.webhosting.uk.com/?s=Moodle
Renders nothing … ie no articles.
Perhaps the closest one may get to AMP stack references related to Moodle is:
http://kb.webhosting.uk.com/uk-website-hosting/linux-hosting/php-web-hosting/
They also have a forum: http://forums.webhosting.uk.com/forum.php
Nothing Moodle specific, but one for PHP and MySQL might help:
http://forums.webhosting.uk.com/php-hosting/
http://forums.webhosting.uk.com/mysql-hosting/
Not saying it's impossible hosting Moodle on webhosting.uk, but looks like it's an 'adventure'.
Best of luck ... 'spirit of sharing', Ken

Thanks Ken and Mauno
I have now got it working but it runs very slowly. I dont have the fastest broadband connection in the world but pages on my site are running especially slowly.
Yes I am hosted at Webhosting UK.
I tried changing php memory in php but that didnt work. Have persuaded Webhosting Uk to increase my php memory to 256M and so site now running.
Thanks for your help and support I appreciate it.

You might have theme designer mode on:
Site administration > Appearance > Themes > Theme settings > Theme designer mode should be unchecked
and check also if
Site administration > Appearance > AJAX and Javascript settings are in defaults

Might also change sessions from DB to file.
Site Admin -> Server -> Session Handling
Comments on the form:
"If enabled, this setting will use the database to store information about current sessions. This is especially useful for large/busy sites or sites built on cluster of servers. For most sites this should probably be left disabled so that the server disk is used instead. Note that changing this setting now will log out all current users (including you). If you are using MySQL please make sure that 'max_allowed_packet' in my.cnf (or my.ini) is at least 4M."
On a remotely hosted shared system bet there are limits/restrictions on DB as well which means one may never get close to a 'faster' Moodle 2 and might also experience some failed functionality as a result (backups and restores of certain courses an example).

Hi,
I have just had an academic with the same issue. When the Turn editing button is clicked (on) the Add an activity or resource link is not a hyperlink, just static text. Turning editing on an off a few times resolved the issue this time.
A thought that came to mind is that we are using the Yahoo YUI Library, if the Add an activity or resource is connected to the YUI could there have been a network delay in calling that?
Just a thought!
Regards
