I’m getting a notice that says; “The cache folder is not writable.” What does this notice mean and how do I fix it?
This folder is created automatically during the installation Connections as it is part of the default plugin folder structure. The folder is required as it is where temporary intermediate images are created and stored. During activation Connections will attempt to make this folder writable, however, some web host configurations prevent this from occurring automatically. To fix this, log in to your site using FTP and browse to the wp-plugins folder and locate the connections folder. Now, set the permissions of the cache folder to be writable by setting the permissions to 755.
NOTE: Some web host configurations require additional privileges, if that is the case, try 767.
NOTE: You might have to first delete the folder, recreate it and then set the permissions.
