Cannot login as admin. I receive a blank page.  I have run update several times.

I assume you have just recently upgraded to CPG 1.6.06
Your problem may be caused by a plugin that is not compatible with CPG 1.6.x
Rename the configuration.php file in each of the plugin folders to something else (like ccconfiguration.php).
If you can login now, the problem is with a plugin.
Rename the configuration.php files back to normal one at a time until you find the one causing the problem.

Thank you for your quick reply. I tried your suggestion. Unfortunately I still have the issue.

If you will PM me with an admin login to your gallery and place a file in your gallery, I will try to resolve the issue.
Place the attached file, unzipped, in your gallery folder. It will allow only me to view/edit your files.

Unfortunately, the file manager is failing to run on your site. Can you check that the file has appropriate permissions (644)?

i just reloaded the file manager.php, permissions are 644.

For some reason (yet unknown) it is failing with PHP 5.6.40 (on LiteSpeed). I tried several methods to get some sort of error messages but none were successful. I renamed your .htaccess file (essentially disabling it) so it is running the default, PHP 7.0 ... and everything seems to be running okay.

I'll do some separate testing on my own servers to try to discover how it could be failing with PHP 5.6.40.

Thank you. It's had been awhile since i've accessed my admin page, so not exactly sure what time frame this all started to fail.
Now that you managed to regain access to my admin page I can create and upload my collection of Mosaic photos.
Many thanks in managing to sort this all out. Regards. Philippe
