Talk:Installation FAQ

Link to jump back to the top

I just added a bunch of questions/answers to the generic FAQ page, and then looked at this to see how it was done (backwards, I know). Clicking on the item jumps you down to the question... but should we add a link to jump back to the top? -- D.I. 29jan06

Nice idea, say jump back to the TOC, I bet even a [[Installation FAQ|Top]] might even work. I think it is possible to force a ToC (by __TOC__ , so the alternative would be to create a section with just the ToC called Table of Contents, then a [[Installation FAQ#Table_of_Contents|Top]] would also work. I will try it --Chris collman 12:47, 5 January 2008 (CST)

Just discovered that Sandbox# or Installation_FAQ# will take you to the start of the page. Using the __TOC__ as an address does not work.

I've just removed all the links to jump back to the top of the page, as the page is now much shorter after lots of FAQ were moved to Errors FAQ. I suggest we try to keep all FAQ pages short enough so that jump links are not necessary. --Helen Foster 05:10, 2 October 2008 (CDT)

Short open tags

Someone said, under : My pages show fatal errors such as : Parse error, call to undefined function: get_string()

"You may also be running a php script which uses short open tags, e.g. instead of <?PHP ?> it uses <? ?>. Either replace short tags with conventional ones, or set this line in php.ini:

" short_open_tag = On"

However, this should never be necessary with Moodle code. If you find any short tags anywhere, file a bug in the bug tracker against the affected code. There are currenly none of these abominations anywhere in the Moodle core code.Tim Hunt 01:19, 26 July 2006 (WST)

Agreed. Such an "abomination" should not be in Moodle core code but the person who deleted it doesn't appreciate the point. This comment was added to help those who are having problems with code which is not part of Moodle core, e.g some of the third party blocks which are mentioned frequently in forums. There is no reason, IMHO, why fellow Moodlers in such a predicament would not turn to this FAQ for help. - Ken Wilson 25 July 06

Sorry, my mistake. I had not reallised that this actually happened with contrib modules. I'll reinstate the that bit (but keep my point about reporting the problem so it can be fixed).Tim Hunt 01:19, 26 July 2006 (WST)

Memory limit limitations

Each method of increasing memory limit has limitations.

.htaccess

directive php_value memory_limit may be disabled by the host

php.ini

no root access

There is a third way which may or may not work:

php function ini_set

Example: ini_set("memory_limit","24M");

It will not work if phpinfo() does not show Configure Command '--enable-memory-limit'

see http://us.php.net/manual/en/ini.core.php#ini.memory-limit

On my host, none of the three methods will work. I am limited to 8M memory per PHP session. I am able run the basic installation. I haven't seen the dreaded error "Allowed memory size of Xxx bytes exhausted" but I expect it at some point.

PHP Debugging Configuration Confusion

The FAQ about getting a blank page during installation refers the reader to the FAQ about checking your error logs, which tells him/her to add ini_set calls to config.php if using Moodle 1.7 or higher. Problem is, during installation there is no config.php file! This leaves the reader in a quandry, and so the instructions should be clarified. See http://moodle.org/mod/forum/discuss.php?d=87473

Installation hangs with zend.ze1_compatibility_mode on

Moodle 1.9 installation fails with php setting 'zend.ze1_compatibility_mode on'.

If you have enabled PHP error logging and if the following error shows up during database setup then turn off the zend.ze1_compatibility_mode in php.ini.

Fatal error: Cannot clone object of class DOMDocument due to 'zend.ze1_compatibility_mode' in .../moodle/lib/xmldb/classes/XMLDBFile.class.php on line 84

If you don't have access to php.ini then edit the config.php and add the following statement just before the 'unset($CFG);'.

ini_set('zend.ze1_compatibility_mode', '0');

Above fix worked for me.

Running a health check

The URL provided seems to be extinct. I get a page that says the domain might be for sale. And offers for vacation and credit card deals!

Thanks James, the health check FAQ has been removed because the code is no longer maintained and it's replicated in checks during install etc. or stated on the Notification page. --Helen Foster 02:20, 26 September 2008 (CDT)
