[SOLVED] Strange database problems with a specific user, after no system change

Hi

I am running 3.1.2.4 smoothly for some time. Even in the last week a new issue of the journal was prepared without any problem.

Nevertheless, a user (also a reviewer) is getting a “something strange happened” popup. In the logs, I can see this:

2020/07/03 16:48:03 [error] 13688#13688: *8992863 FastCGI sent in stderr: "PHP message: PHP Warning:  Declaration of CustomHeaderPlugin::register($category, $path) should be compatible with LazyLoadPlugin::register($category, $path, $mainContextId = NULL) in /home/linguamatica/root/plugins/generic/customHeader/CustomHeaderPlugin.inc.php on line 0PHP message: Slim Application Error:

Any idea what might be going on?
Thank you

But great it is fixed.
