How to resolve the Fatal error: Out of memory problem in vBulletin?
If you see an error message similar to the following one:
Fatal error: Out of memory (allocated 11111111) (tried to allocate 1111 bytes) in your_php_file.php on line 111
it means that the execution of the above php file needs more than the allocated memory.
A possible workaround is:
1. Open your vBulletin include/config.php file.
2. Below the php open tag add the following line:
ini_set(‘memory_limit’, ‘128M’);
The code will look as follows:
<?php
ini_set(‘memory_limit’, ‘128M’);
In this way, you will increase the memory limit for your script to 128MB.
The same solution can be applied for different scripts. You should paste the above code in a file which is always invoked when the script is executed. Usually, such files are the configuration ones.
