I have been working on this website for awhile then noticed one day that when I changed some meta information for a photo (Title) and clicked Update that I got a 404 error and the new information was not saved.
I also cannot update settings for plugins. Same thing, 404 error.
I can however add new photos and update poss and pages.
I noticed that the backups for the site went from 35MB to about 402MB around the same time I started seeing the problem. I've added about 10-15 new photos, but they were low resolution and I wouldn't think that they would cause a 10x increase.
I tried optimizing my tables via ManageWP, didn't fix it.
Scanning through similar threads, I found information and increasing the memory limit by adding
define('WP_MEMORY_LIMIT', '96M'); to the wp-config.php and wp-settings.php files. This did not work.
I also created a php.ini file in the site's /public_html folder with the code
memory_limit = 92M in it.
I've read some threads about some server security mod updates and fixes, but couldn't find specific code. Would I need to talk to my host about this?
Any thoughts on how to solve this would be greatly appreciated.
