Installed Hesk on my local server for customisation and testing, before installing it on a clients server. Mods for Hesk v 3.0.7 is installed as well. All is working fine, on the clients side, tickets can be opened, closed, replies added etc.

When opening a received ticket as admin I am getting a blank screen.

Debugger info:


I can't post the code here for whatever reasons, thus the image.

Any help is appreciated, thank you!

I haven't seen this before, but this is not an error that HESK generates and probably also not something your web server generates.

Are you using some very old version of Firefox (there seems to have been a similar bug quite a while ago)?
Do you get any different info if you turn "Debug mode" to ON in Hesk settings?
Do you get any more info in server error logs?

Thanks for your reply, Klemen!

I am using Firefox 52.0.2 on macOS Sierra. Tried it with Safari 10.0.1 as well, same result.

Also there is no different info if debug mode = on.

The console is showing me:

GET http://localhost:8888/support/admin/admin_ticket.php [HTTP/2.0 500 Internal Server Error 964ms]

This will need to be debugged from the server logs because the server is returning the error, not Hesk.

Got the following info from the server logs:

PHP Parse error: syntax error, unexpected '[', expecting ')' in /home/public_html/support/admin/admin_ticket.php on line 473, referer: http://localhost:8888/support/admin/admin_main.php

Line 473 reads:

$childRs = hesk_dbQuery('SELECT * FROM `' . hesk_dbEscape($hesk_settings['db_pfix']) . 'tickets` WHERE `parent` = ' . intval($ticket['id']) . ' AND `trackid` = \'' . hesk_dbEscape(hesk_POST(['childTrackingId'])) . '\'');

This code isn't in original Hesk, I'm moving this to the "Mods for Hesk" subforum, maybe Mike knows more about this.

Thank you very much Klemen!

This was reported earlier this morning on the MFH GitLab repo. Check out https://gitlab.com/mike-koch/Mods-for-HESK/issues/560.

Thank you Mike, that was the solution.

Everything is working fine now!
