The link that you are using for the installer stub is incorrect.  Do not use the public_html part in the URL.

I installed the stub file in the coppermine1 folder on my website and loaded this address into my Firefox browser: https://www.rosenblums.us/public_html/coppermine1/cpg_installer_stub.php

I waited a few minutes with no response in the browser window. I then tried to login with the link : https://www.rosenblums.us/coppermine1/login.php

I got the same error message: Fatal error: require(): Failed opening required 'include/functions.inc.php' (include_path='.:/opt/cpanel/ea-php73/root/usr/share/pear') in /home4/rosenblu/public_html/coppermine1/include/init.inc.php on line 134

Hello,

I am using 1.6.20 for quite a long time now and - by the way - I am very happy that this great gallery exists.
The web hosting I am using changes from time to time the PHP versions. At the moment it's 8.1, next year 8.2, probably 2026 then 8.3 (I guess).

I am not a tech or internet expert so I usually only change the Coppermine when I have to. So my question is:
a) if php 8.2 or 8.3 will also be possible with Coppermine in its newest version
b) if perhaps those php versions are also still possible with 1.6.20?

(I changed some minutes to 8.2 and it seemed to work but as this was a public online test I changed it back to 8.1)

It would appear that your installation has been corrupted to have missing files. You could try using the cpg_installer_stub to freshen your installation.

I am running CPG 1.6.18 on PHP7.4 and have not used it for about a year. I tried to open it today and got the following error message: Fatal error: require(): Failed opening required 'include/functions.inc.php' (include_path='.:/opt/cpanel/ea-php73/root/usr/share/pear') in /home4/rosenblu/public_html/coppermine1/include/init.inc.php on line 134

What should I do to fix it? Thanks.

I suspect that the md5sum in cpg16x.files.xml for init.inc.php also needs to be updated in the repository.

Thanks, John  ...  corrected. 

Reinstallation using the stub solved the problem for the most part.  Most of the errors no longer appear.

However, now Versioncheck reports that include/init.inc.php is either corrupt or was modified.   I looked at its md5sum hash in cpg16x.files.xml, and it doesn't match the file.   When I corrected the hash, Versioncheck still reports that the file is corrupt.   Obviously it is NOT corrupt because everything works, and I did not modify init.inc.php.

Line #5377 of cpg16x.files.xml:
The incorrect hash was:             3cb6e66a5a4d5b33078d58fb7c46b48c
The hash I replaced it with was:  521d42c772634747b266921e89c37472     <-- derived using md5sum include/init.inc.php
No <Tags> were disturbed.

Versioncheck still reported "File may be corrupt...", but when I re-ran it after selecting  "Do not connect to the online repository", the discrepancy disappeared.    I suspect that the md5sum in cpg16x.files.xml for init.inc.php also needs to be updated in the repository.

Many thanks!

Yes, you can ignore them. There was an oversight in packaging the 1.6.26 release. It will be immediately corrected.
You can use the cpg_installer_stub to re-upgrade to 1.6.26, if you choose.

I upgraded from 1.6.20 to 1.6.26, ran database update, and Versioncheck.

Versioncheck says I now have version 1.6.25 installed, and produces the following discrepancies:

(see attachment)

There doesn't seem to be any problem with the gallery functioning, but I don't use all features.

Can I ignore these errors?   I'm thinking that perhaps it's an error with Versioncheck itself and not my installation.
