Joomla! Discussion Forums

Hey there,

Joomla beginner here. It's been going really smooth barring a couple of fuckups, but I've found my way out so far.

Here's the latest -


Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 40 bytes) in /var/www/html/joomla/includes/domit/xml_domit_lite_parser.php on line 78

It happens when I click on Menu>mainmenu.

Thanks in advance.

Hi,

Your server has a limiit on memory usage, and your Joomla installation is exceeding the limit.
What have you installed that is particularly intensive?
Go to the /administrator/ backend and unpublish any recently added modules.
You might first try running phpMyAdmin and seeing if you can't optimise the database - this might reduce load.
On the structure tab - click the 'select all' under the list of tables, and in the drop down select box click repair.
Do the same again and this time click 'optimise'.

Dean.

I suspected so to begin with. I had deleted/uninstalled many modules and components that wasn't required but this is still happening.

This is happening only I click on "mainmenu", everything else is working totally fine. "mainmenu" has entries going more than the first page of 30 items. Could there be a preset limit for that in the db?

I get a 500 internal server error if I don't get that fatal error mentioned in the first post btw.

I'm going to go to my phpmyadmin page sometime this weekend.

Hey Dean,

I've removed a lot of modules and components like I said above. I even cleared those rows from the database.

The repair and optimise went off peacefully but I still get

"error 500" or 

Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 41 bytes) in /var/www/html/joomla/includes/domit/xml_domit_lite_parser.php on line 134

when I try going to "mainmenu" from the admin backend panel.

I'm actually using the same db as the existing one thats used by phpbb, btw. In all there are 83 tables, 995901 records and 37 MB. This is one db. There's another test db worth 30 tables - unused. So 2 out of 5 allowed DBs are in use.

So what do I do here next?

The error 500 is an entirely different beast from the memory error.
The memory error is best solved by raising the memory limit in php.ini - if you have access to, and control or, this file.
You may be able to override this setting in .htaccess - I am not sure, its not really my field - although I dabble.

Did you recently enable SEF Urls - is that related in any way?
Checking server logs should prove useful, see if you can see what the 500 errors are about.
It could simply be that the memory limit is being hit early and the error output is coming before the http headers are sent, causing the server to see 'illegal' output. Then again it could be something different.

As I said, raising the memory limit is the 'easiest' option.

Dean

I should mail my webspace provider about this then?



Some htaccess king please see this and help!



YES! If I remember correctly I enabled SEF urls 2-3 days back and I'm pretty sure this problem started to happen during the same time. I've disabled it right now but the problem persists.



Here's what I dug out yesterday

I have to get this fixed urgently. Thanks a ton for the help!

File does not exist is fairly categoric.
It looks like you have a missing file, perhaps something went wrong during FTP upload.
Another possibility is that your .htaccess is 'redirecting' the call to the wrong location.

Adding this line to your .htaccess file  should increase memory limits
php_value memory_limit 16M

This topic may have been posted over 45 days ago, but DeanMarshall's answer was still helpful to me.

I couldn't get in Main Menu, on the admin back end. Probably due to a recent VirtueMart install.

I simplified my config as much as possible, then DeanMarshall wrote an easy fix is going to .htaccess (see above) and adding the line below.

php_value memory_limit 16M

I just added it to the very last line of .htaccess, clicked save and got in main menu.
