I get a white screen on GUI

I upgraded to the latest version of PBX and now when I log into the GUI I just get a white screen. I have read other post and nothing seems to work. Please help me.

In order to assist you you would need to provide the output of amportal a dbug when you try to login to the GUI.

Your issues comes from Endpoint.Try the following:

cd /var/www/html/admin/modules
rm -Rf endpoint

Then try to log back in. If you use the commercial endpoint manager, you should be able to grab the latest version via module admin, as I believe this issue was resolved early last week.

Thank you so much!!
I was able to disable endpoint because I was scared to removed it completely. I was then able access the GUI. It was still telling me to update the endpoint manager so I was able to do so.
Do I need to enable the endpoint again? Or whats the difference between the two? Endpoint and Endpoint manager?

Whether or not you need to enable endpoint, depends completely on whether you have purchased and licensed the module already or plan to in the future.

As for the difference between Endpoint and Endpoint Manager, endpoint is a paid commercial module written and maintained by Schmooze Com, Inc. whereas endpoint manager is opensource and available via git.freepbx.org. The commercial endpoint module supports upwards of 200 devices with additional devices constantly being added. Should you like to learn more about the commercial endpoint module, you can find documentation on our wiki or you are always welcome to reach out to our sales team.
