As per the topic, it happened when I tried to update the plugin and the update failed. After that, I went into FTP to see if the plugin is still there. It is, however there's only 1 folder called 'tmp'
No matter what I did (delete, open or even change the CHMOD number), the same error always comes up:
Header of the error: "Error listing directory '/xxx.com/wp-content/plugins/wponlinebackup/tmp'"
In the body of the error: "Could not retrieve directory listing
Can't change directory to /xxx.com/wp-content/plugins/wponlinebackup/tmp/: Permission denied"
I don't know whether it's the plugin or is it something to do with my host that's causing this?
I tested with backing up when I first installed the plugin and it worked fine. I even managed to download the zipped backup file. Everything's okay until now.
Any assistance greatly appreciated, thank you!
