Blank Popup Issue

kingfash1

Hello,
I get black with popup when trying to create new ticket, everything was working until last week. Please help.
Attached are the screenshoot.
KevinTheJedi

You will need to check all logs (general server logs, webserver error logs, PHP error logs, MySQL/MariaDB error logs, osTicket System Logs, Browser Console logs, etc.) for any related errors.
Cheers.

Thank you for your response @KevinTheJedi below is the error, I got in the browser console:
"Failed to load resource: the server responded with a status of 500 ()
scp/ajax.php/users/lookup/form:1 "
I don't what to do,.
Thank you.

Keep looking at other log files. 500 is generic and a real error should be logged in PHP error logs or webserver error logs.
Cheers.

Those are just deprecation warnings; no errors there. Keep searching for errors. They will be somewhere. You can even try updating your bootstrap.php file and setting display_errors/display_startup_errors to 1. However I don't recommend this on a live production system as it will output errors on screen to users, etc. which can prevent things from functioning correctly, can be a security issue, and simply just doesn’t look good.

Things generally dont break for no reason.
Likely something like changed.
What was it?
Did you do an OS update?
Update Apache?
Update PHP?
osTicket update?
add a new Plugin?

Thank you for your response @ntozier . My server is a dedicated server hosted online, and it was recently upgraded to one with larger disk space by the hosting company. It is also running other business applications. I did a fresh install on a subdomain, but I got the same error. I guess it has something to do with the new server, but I have no clue what to do or what to tell the host.

Always check your various logs for any related errors (general server logs, webserver error logs, PHP error logs, MySQL/MariaDB error logs, osTicket System Logs, Browser Console logs, etc.).
Cheers.
