[SOLVED] Installing bot_subs_300.zip

I've been working through the installation of CBSubs plugins (first time to use CBSubs) and am attempting to install the content protection plugin per the instructions on pp. 129-130 of the manual.

When I use the joomla backend extension manager to install bot_subs_300.zip, I get this error:

JFolder::create: Could not create directory
Warning: Failed to move file!

Can you point me in the right direction?

Permissions issue typically. Check Site > System Information > Permissions and ensure all is green. If not then fix the permissions as needed. Often the tmp and cache folder paths are incorrect, which you can correct in Joomla global configuration.

I had three unwritable (red) areas: configuration.php, Log directory and Temp. I see the configuration.php permissions are off, but the permissions appear to be the same as the green areas for logs and tmp:

drwxr-xr-x 2 jfb7916 pg1988976 31 Apr 26 13:12 cache
drwxr-xr-x 16 jfb7916 pg1988976 4096 Aug 13 11:44 components

drwxr-xr-x 2 jfb7916 pg1988976 31 Aug 13 13:29 tmp

(I removed several lines, just for a more concise view.)

chmod 644 configuration.php has no effect (still red). I'm guessing that there's another username trying to write to these files?

Log directory and Temp

Those two are your main concern. Specifically "Temp" as it's where Joomla will attempt to move the install package after upload. You need to ensure the path to your Temp directory is correct within Joomla global configuration. You then need to ensure it's completely write accessible (usually 755 should be fine, but you can try 775). Most likely though the path to the Temp directory is just incorrect.

The paths are fine — checked and rechecked. Something's not right, though. I temporarily set the configuration.php file to 777, logged out of the backend and came back in, and it still showed as red.

It's fine to ignore configuration.php write access check. It won't hurt the upload process. You need to ensure the Temp path is showing green now.

It's either failing to move from PHPs tmp directory to Joomlas temp directory or failing to move from Joomlas temp directory to plugins/system/cbsubsbot/. Ensure plugins/ and plugins/system/ permissions are also set correctly (should be 755, but can try 775).
