I am receiving an error from a file in one of the Concrete libraries all of a sudden on my webpage and do not know why or how to correct it please provide me with Some assistance. The error I am receiving is:
Catchable fatal error: Object of class BlockRecord could not be converted to string in /home2/simpstai/public_html/concrete/libraries/3rdparty/Zend/Cache/Core.php on line 361

If something like this suddenly starts happening on a site that has been happily working and stable, look for changes in the host environment. Most common at present is updating the php version without telling you.

In the mean time, as the problem appears to be in the retrieval of a cache record, you could try clearing the cache. You may be able to login directly to the dashboard at yoursite.com/index.php/dashboard. If not, you should be able to use the host cPanel to empty the directory /files/cache/ (but that won't clear the block cache)
