Php photo gallery TWG | JFUploader | TWG Flash upload | WFU | Forum

This morning I got the following error:

Fatal error: Call to undefined function checkfullscreen() in .../public_html/twg/index.php on line 104.

I have not changed any files, and it has been working OK for many months. Could not find an obvious fix so ran the patch to update to 1.8.4 and still get the same error (now at line 106). I cannot find the function checkFullscreen() in the code, but all permissions seem OK and twg info.php says everything is OK. I get a similar message if I try to go into the admin page.

The site is www.dpfr.org.uk/twg

Thanks

John

Why do you post AND send an e-mail to me?

I've been getting the same error for a while now:

Fatal error: Call to undefined function checkFullscreen() in /home/trentham/public_html/photoalbums/twg/index.php on line 108

If I copy all the files across to my website from a backup (excluding Pictures and cache folders) twg works fine again for a couple of days, but then the same error message appears again. During that time, I have not added any new photos.

The errorlog file contains the following entries:

Any help to solve this will be appreciated.

which TWG version do you use?
And which php version do you use?
Any errors in the server log?

I am using twg 1.9
Php version 5.3.27

I currently get the following error when trying to access admin
http://www.trenthamunited.co.nz/photoalbums/twg/admin/index.php
Fatal error: Call to undefined function a() in /home/trentham/public_html/photoalbums/twg/admin/_include/init.php on line 228

The following message is in my site errorlog
[Thu Sep 05 20:47:56 2013] [error] [] File does not exist: /home/trentham/public_html/404.shtml, referer: http://www.trenthamunited.co.nz/photoalbums/twg/admin/

do you have any blocked functions (see php info)?

The strange thing is that it worked for a few days. Has your hoster changed something?

Best, Michael

I am not aware of any changes by the hosting company.

I've copied the admin folder from a backup and that has fixed the problem for now.

If this happens again please compare the two version. I really want to know what causes this problem.

Best, Michael

Thanks Michael. I'll post more details when/if it happens again.
