Cannot delete any plugins or change widgets

Try:
– switching to the Twenty Eleven theme by renaming your current theme’s folder in wp-content/themes using FTP or whatever file management application your host provides.

– resetting the plugins folder by FTP or phpMyAdmin.

Tried all of that and no change

This happened after i installed 2 new plugins which i deactivated and no change

The other change is an increase in php.ini php memory to 3000mg and post max file size to 3200

could this cause it?

3000mg?

My host suggested 3000mg

doesn’t have a limit

I guess you don’t have a solution

Try using:
php_value memory_limit 64M

in php.ini
