Connection lost after saving

When making changes through modx it now goes to a connection lost page quite often. It doesn't matter what the change is and it come back on its own as well. This is from the error logs for today when it crashed.

[2017-07-18 20:07:33] (ERROR @ /connectors/resource/locks.php) xPDO->removeObject - Error deleting modDbRegisterMessage instance using query DELETE FROM `mod_register_messages` WHERE ( `mod_register_messages`.`topic` = 1 AND `mod_register_messages`.`id` = '66f041e16a60928b05a7e228a89c3799' )

[2017-07-18 22:04:55] (ERROR @ /index.php) Could not cache resource 50

Any ideas on how to resolve this issue would be greatly appreciated.

Thank you!

I'm also working on this project. In many cases once the server respond it will go down again after I make another edit and save it. It basically does this until I give up. Both the website and the Modx CMS both go down.

Any ideas would be greatly appreciated!

Thank you.

Is it possible that your database is overloaded and failing to respond?

Another possible culprit would be that the content of what you're saving is violating a mod_security rule.


Are you using the MODX Manager's messaging system for users to communicate with each other? If so, are you using the MessageManager extra?
