Editing K2 Items showing error

Question

I am running K2 (Version 2.7.1) on a local instance of WAMP running Joomla 3.6.2. I was able to edit K2 items perfectly, but suddenly this morning, when trying to go into K2 (just the items) I'm being shown the following error (reporting is set to maximum):

Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 17312936 bytes) in C:\wamp\www\client_sites\sitenameremoved\libraries\joomla\application\web.php on line 763

I have rebooted WAMP and the PC it's running on, but can't work out what's changed. This error has only just started showing.

Answer 1

Ok, so it turns out this wasn't an issue with Joomla or K2 at all, but an issue with WAMP. I increased the PHP memory limit in php.ini to 512M and edited the index.php within the root of the Joomla install and added the following:

ini_set('memory_limit', '512M');
