Hello,

I am not a programmer so I do not know where to begin.  I have followed the instructions to get this much done.

And I am sure that I caused this problem but I do not know how to resolve it and I cannot make any changes to my course.

I am using moodle 3.2, I think

Please tell me there is someone that I can pay to fix this.

Coding errors (or coding_exceptions) are problems that are probably caused by incorrect code. For example a plugin that does not communicate correctly with Moodle core.
These errors are normally not caused by incorrect user input or temporary problems like the connection to the database server being down.
As with all error messages, it's a good idea to search moodle.org and the tracker to see if anyone else has reported the problem.
One user posted that sometimes, if you purge all caches the error message might disappear!
Block type ... has been disabled by the administrator
See the discussion Coding error detected, it must be fixed by a programmer: Block type admin has been disabled by the administrator. for a possible cause of the error plus solution.

Hopefully you've investigated and found that there are lots of Moodle specialist companies who can provide commercial support so this problem may be resolved now.

If not we'd need some more details to help you troubleshoot this issue.

Is your site working at all? E.g. does the main page load OK and can you log in? Is it only certain actions causing the error messages?

You say you think you caused the problem, what might have happened to suggest this? Is this a new site or a previously-working site that now has a problem.

When you say you deleted the cache is that on the Moodle server or your computer? I'm wondering which operating system is being used for the Moodle server?

Could you post screenshots of the error messages and what actions led to these (e.g. trying to view a course or specific activity).

Did you recently install a theme, or upgrade to a Moodle version where your current theme isn't compatible?
