Hi there I have tried to install plugins Disqus and Premier Promotion. Both installed fine, but when I try to update settings, get blank page when clicking save (or Error 500). As it is not working, I tried to uninstall in but get the same error. Everything else seem to work fine at the moment. Tried another plugin as well (can't remember which one) and it did the same but at least I was able to delete it. The BIG problem I have now is that I can't change any setting unless I delete the plugins. Perhaps I installed old/non-working plugins. A pity because both these are quite nifty to have.
