This error occurs due to a session overload space from your domain. Simply clear out your session folder (don't delete the folder) and also clear out the OpenCart's cache folder. Then, refresh the page on your browser. It should correct the problem.

Since this isn't an OC issue, ask this question to the web hosting technical support. They should be able to provide that information in order to resolve this problem.

Moving to a new hosting company resolved the issue.

add it to the index.php in your admin folder

by doing that and deleting the php.ini file I got rid of the message from the admin, but not from the front end

Ensure to have no space before the <?php and after the ?> in the file.

I was getting the similars errors while upgrading to 2.2.0.0 from 2.0.3.1 and I tried below the tricks

1) Deleting PHP.ini
2) Deleting System Cache
3) Deleting Theme Cache
4) Deleting Vqmod Cache

I did help me in getting rid of some of the errors. Now I don't see any errors of front-end of the website and I can now log in to Admin Panel but now I don't have the permission to edit anything.

You seem to be using the old version of index.php even though you upgraded to Opencart v2.2.0.0 release. This release now uses a framework file in order to register the objects as it no longer uses the serialization by default but rather json encoding / decoding method.

Either something went wrong when upgrading your database or the database upgrade were successful but you did not replaced the files with the new release ones.

The most generated errors being found on Opencart forum originates from contributed programming.
