For the last few months, I get 'Error 500 - Internal Server Error' every time I try to update WordPress or any of the Plugins. I have two sites and get the exact same error for both, I assume there is a problem with my hosting company. I believe the error started right after I upgraded to WordPress 3.5.
I should add that everything else with WordPress seems to work just fine. I can post new posts or pages. I can even install new Plugins. I just cannot update WordPress or the existing Plugins.
Any help would be greatly appreciated.
