Hi,
Iīve been looking into this for many hours and canīt find a solution.

I canīt install a language pack in CE 5.2.0e and get an error instead. The weird part is that I had installed a lang pack a couple of weeks ago and I just installed an inbox-dashlet and that one went well...

The error Iīm getting is
Warning: copy(/home/xxxxx/public_html/scrm/./install/language/es_es.lang.php) [function.copy]: failed to open stream: Permission denied in /home/xxxxx/public_html/scrm/modules/Administration/UpgradeWizard_commit.php on line 257
Could not copy file /home/xxxxx/public_html/scrm/cache/upload/upgrades/temp/PXbC4O/./install/language/es_es.lang.php to /home/xxxxx/public_html/scrm/./install/language/es_es.lang.php
The "cache" folder and sub-folders are 777.

But... I did notice this:
- The folders inside ~/cache/upload/upgrades/temp/<random> (which I understand are created upon add-on installation) do not get 777 as permissions, instead they get 0 according to my ftp client and 2770 according to the file manager in the admin panel. (This is a paid hosting service, and I donīt have ssh access.)
- Also, I can not browse those random subfolders, and I have the feeling the system canīt even decompress the files in there, and therefore canīt copy them over afterwards.

Any help would be great,

Thanks in advance!
HQ.
