I've been working on this wordpress website for a long long time now, but recently it stopped working. Well, it still works, but loading a single page (or homepage) takes over 3 minutes, or it doesn't load at all (500 internal server error).
It is concerning this site:
I've got the same problem while trying to log into the admin panel.
I've got a big number of posts and pages, but it all worked fine until I installed All in One SEO pack plugin.
I've disabled this plugin, but still the site won't load.
I know I am still running an old wordpress version (3.3.1) but since it's loading so slow, I don't dare to update it via the wordpress panel.
My active plugins: (17)
Bliss Drive Hit Counter Plugin
Contact Form 7
Contact Form Plugin
Exclude Pages from Navigation
Facebook, Twitter, Google Plus One social share buttons for WordPress
Featured Content Gallery
GoGadget Weather and Weatherforecast Widget
Jetpack by WordPress.com
News announcement scroll
Simple Feed List
Smart Youtube PRO
Social Sharing Toolkit
Does anyone has any clue how I can fix this? I know there are a lot of 500 error solving posts around here, but can't find one who also sometimes loads.
Any help would be greatly appreciated!
Thanks in advance!
