As far as I see you have version OJS 3.0.2.
Did you change anything prior to this error in configuration/settings, deleted some files or in phpmysql?
No I didn’t.
I don’t know whether they have done anything at a hosting level.
But I’ve done nothing
Do you suggest replacing or adding any ojs file?
I would strongly suggest upgrade to OJS 3.1.0-1 since OJS 3.0.2 has a lot of issues. I see that your installation is fresh so it is better to do upgrade now and add issues and articles later than work with OJS 3.02 and do upgrade later.
I understand that the update is necessary. The question is whether it is safe to perform such update if the current system has problems, it operates abnormally.
We also use 3.0.2 and two days ago faced with an unexpected problem. Elements of the administrative interface are not loaded, just rotating circle:
I checked all the logs, no fatal PHP errors. I will be happy for any help in solving this problem 
When you do upgrade all files are replaced and database upgraded so if there is any issue with any of files it will disappear since upgrade replaces old files with new ones.
I agree with resolving files issues during upgrade, but I’m afraid that in my case there’s some inconsistent data in our database
I remember another problem (https://forum.pkp.sfu.ca/t/tasks-not-loading-for-certain-users/32074/6) with “permanent loading”. Now I checked the solution proposed then and found 3 submissions without section_id. I corrected this in the database. But this did not change anything - as before, nothing is working inside the system
Please be specific. Post screenshot and phperror log.

I just replaced the real domain names by “…” when I posted the log here. No files in OJS were deleted, nothing changed in addresses, URLs, links, etc. All public sites for all journals work perfectly, absolutely no problems. Problems start after login…
Any help would be greatly appreciated, thank you! We are really in trouble now. We were going to update OJS in early March, but in this state of the system I’m really afraid to update
Please be always consistent in all requirements since , in my experience, many people use obsolete php version, do upgrade on the top of existing files , not setting php.ini properly and they do have a number of issues.
Thus, high quality preparation is 90% of work.
I upgraded several installations and mostly it went easily.
By the way, I do not see anything serious in log that you posted.
Did you deleted all files except config.inc.php and folders with data and /public folder before update?
Thanks
Actually we did not update to 3.1. Our 3.0.2 was installed last April and since then it has been working properly. We were preparing for the upgrade, but we faced with this problem on the running system. I believe that we need to solve it before updating to 3.1.
What kind of changes have been made on server since it worked properly?
Do you have option to set php as 5.6.30?
We discovered the problem last Saturday. No changes were made on the server side, only the regular work of editors and managers in different journals.
Did anyone changed something in database such as collation or collation of connection with server? You can check that by comparing charsert/collation of connection with server and collation of tables in database. if you use phpmyadmin you can check that easily.
No, we did not make any changes from our side at the database level.
