Failed to open stream - Debugging

I have turned debugging on after having had some issues with the site and I get these errors. Only recently I upgraded to moodle version 3.10. 

The first two warning are the same. Any help is appreciated.

In the Moodle source code folder have you got a folder in the mod folder called tiles? What does it contain?

Moodle doesn't have a mod/tiles folder and I don't know of any plugin that goes in that location. There's a Tiles course format plugin but that goes in course/format/tiles.

Hi Leon,
I have tried looking everywhere to find the culprit that is messing up the site. I have turned debugging on and now I am getting this.

I spoke to the host and they said that it is an issue within moodle and that everything is fine on their side.
Do you have any suggestions?

Thank you.

Try purging caches: under Site administration ▸ Development ▸ Purge caches click Purge all caches. Does that fix it?

Yes, I got rid of all the debugging messages by purging the caches, but whenever I try importing questions using the Aiken format, I get the error
Invalid permissions detected when trying to create a directory. Turn debugging on for further details.

Plus when running cron (don't know if this helps) I get this

Well you can enable debugging and post details here (or in a new discussion if it's not related to this issue).

But it sounds like it goes back to this reply: Moodle's PHP scripts read and write to files in Moodledata as a user account. This user account must have the correct access. I have no experience of managed hosting using Windows Server so I don't know how to set this up. The site cron should be run as the same user account otherwise this can be trying to read and write files in Moodledata as a different user account.

Do you think I should reinstall moodle? Maybe this would help solve all the issues I am having.

Did you get anywhere with the above about the lock only I have exactly the same issue. I too was thinking about installing a later version of Moodle in the hope that it took the issue away, but when I looked at the code in the above file it looked the same in both versions to me.

Ok. So , I reinstalled moodle once again. This time I try to upload a file using AIKEN format and I get a bit more info on the error.
