It seems like someone is having trouble with their website. Maybe I can help: go fish : Being dramatic always helps.
A 500 error usually happens when the ‘programs/scripts …’ that are executed when a page is requested fail unrecoverably, for example Java Exceptions or any errors in a perl script that cause furhter execution to fail.
You should have a way of accessing your ‘error_log’, if there is none, the FAQ says you can turn it on. Try to access your site and then check the latest entries in the error_log. This should give you a good hint where the page request fails.
I have had this problem before. The first few times it’s a bit of a hassle to find the error.
Hope you’ll get your blog back to work. Otherwise just contact me here at my blog. I cannot seem to post comments to ‘go fish’ from my home computer.
