Ioncube permission error

[janiosarmento]

I updated my WHMCS installation, but all I got was a BSOD.

Checking the logs I found:

[Tue Jan 22 10:05:52 2019] [warn-ioncube] mmap cache can't open /home/meuportofacil/public_html/vendor/composer/../mtdowling/jmespath.php/src/JmesPath.php - Permission denied (pid 2063

I checked entire account permissions (ran a script to chmod files to 644, directories do 755, and set correct owner to all of them), tried even chmod 777 (I know), but the error remained.

So, I had to rollback to previous version.

Any suggestions?

Hi @janiosarmento,

A permissions mask of 644 is fine for the PHP files.

From my research the other possibility cause of this error is user/group ownership of JmesPath.php: https://forums.cpanel.net/threads/mmap-cache.577221/

The correct user/group will depend upon your specific server configuration. But for a fairly stock cPanel server, the file ownership and group should be the same as the user directory name.

Eg. On a cPanel box with the WHMCS files at /home/david/public_html/ files should be owned by david, and the group should be david.

Thanks for your reply.

As I said before, I adjusted all permissions, including file owner, exactly as you suggested.

But no success.

I opened a ticket, I hope someone from technical support would be able to help.

Hi @janiosarmento,

As this is a server configuration matter, the assistance we can provide will be limited. But we shall do our best!

Please bear with us as following a new release is our busiest time.

I understand that you state it is a server matter, but I don't understand why WHMCS 7.6 works fine, but WHMCS 7.7 fails to run.

It is the same server, in order to put my site back to track I just did `rsync --delete` from my backup to live server.

I hope I don't get stuck on an older version forever... 😕

I managed to solve my issue. Actually, I can't explain what really worked, or why, but that's what I did.

First, I decompressed the full release zip file on my own computer.

Then I rsynced the files from my computer to server:

rsync -vaPtrz ~/my/whmcs/location/whmcs/ root@my.server.ip:/home/myuser/www/

I think the key here is retaining the same permissions inherited from the zip file.

Then, I had to ssh my server and run:

php ~/myuser/www/install/update.php

That was because I got stuck with a screen stating my database mismatched version with installed files, and it was not possible to run it within web interface.

From this point on, it was just a regular update, with a few "next, next, finish" clicks.

Thanks for everything.
