Well- after going through all my plugins it seems the problem is coming from the AdSense-deluxe plugin– one of my staples. I was running version .7 and upgraded to .8 but problem is still there.
When the plugin is activated I get the 500 internal server error whenever I post or edit .. although the posts will be added . I cannot delete posts, period.
I can’t see that anyone else is having this issue. If someone can think of how to solve this-please let me know – I would be very grateful.
