Trouble connecting one site, others no issue

Support

Hello,

We are having trouble connecting one single site to the mainwp, setup goes as normal. And first gives a succes back, but after that first contact it loses its connection.

Everything is up to date, and we also tried to revert back to a original WP theme, and disabling all plugins except for MainWP child.

The only error I am able to trace is:
[11-Dec-2025 15:45:36 UTC] PHP Notice: Function _load_textdomain_just_in_time was called incorrectly. Translation loading for the mainwp-child domain was triggered too early. This is usually an indicator for some code in the plugin or theme running too early. Translations should be loaded at the init action or later. Please see Debugging in WordPress for more information. (This message was added in version 6.7.0.) in /htdocs/**.nl/wp-includes/functions.php on line 6131

Does anybody have a similar issue?

Thanks in advance

Hey @FrankMHP

That PHP Notice is not related to your connection issue.

Please elaborate on this.

What exactly is successful - Connection Test, or adding the site to the Dashboard?

What do you mean by first contact - perhaps a sync after the site is added?

Please provide any error messages you see in the MainWP Dashboard, and add screenshots if possible.

Hey Bojan,

Happy new year.

Its an issue that we cant replicate anywhere else, only with this site. And then also with plugins and theme’s turned off.

Reconnecting works, and shows succesfully. Come back later, and its disconnected.

And after we are back to square one.

If you need any further information, please let us know.

Thanks in advance

Frank

Hey @FrankMHP

Thanks for the additional info.

Please open a private Help Desk ticket so we can review the MainWP logs to see if anything relevant is logged during those disconnects.

Please refer to this Community thread by its URL in the ticket.
