wp-openid suddenly stopped working and broke wordpress

Hi, I’ve been using wp-openid for a while, when today I tried accessing the blog and no posts and no pages could be viewed. There wasn’t exactly an error message, as wordpress somehow thought it was empty.

I couldn’t view them neither on the frontend nor on the backend, database was fine, so I decided to deactivate all plugins after which it was working again, so I tried every single plugin alone and it turns out wp-openid was the culprit.

I can’t explain what happened any better, I did not install any plugin, any theme or anything else for that matter. It happened literally out of nowhere.

I of course tried deleting and re-installing it but the problem remained the same.

Is there anywhere where I could possibly find the reason for this breakage?
