Thanks again for taking care. The widgets look fine.
I was making the final tests before upgrading the production site.
Guess what? I bumped into featured images failure. All 4 small images, something like 250x170 px, which I used for testing, become stretched. See the backup site.
But the most terrifying thing is that I got:
"Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, email@example.com and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.
Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request."
while working on featured images. That problems seems steady, it happens at least five times and I was waiting for the server to come back alive. I was able to set only two featured images before giving up.
In the end, I gave up and switched to the default "Twenty Twelve" WP theme and set another two featured images. There was no Internal Server Error message while I was working on Twenty Twelve.
Listen up, I will set up an out-of-the-box WP 3.5.1 and your latest CC version. No plugins, just a vanilla plain install. I would try to set featured images there and let you know whether Internal Server Error message comes or not.
By the way, I have checked logs for the errors, there was nothing for January 28.
I will be in touch :)
Take care, Konrad.
Thanks again for all your efforts.
