Cannot start FileZilla

You can reset FileZilla to defaults by making sure that all copies of FileZilla are definitely closed and then running the following command:

mv -v /home/superuser/.config/filezilla/ /home/superuser/.config/filezilla_bak

Then reopen FileZilla which will build a new, clean set of local preferences. This should be enough to get around what is more than likely a bad, local configuration file.

I had the exact same issue. I presumed there was an issue with the filezilla.xml file. I went to /home/$USER/.config/Filezilla/ deleted the old filezilla.xml file.

Then went back into the terminal and typed "filezilla" to open the program. For me, it opened fine and it created a brand-new default XML file in the old file's place. The site manager options are not affected by this as they are in a different file called "sitemanager.xml" which is in the same directory. So the program opened as a fresh new program with the same site manager options as before.

Go to ~/.config/Filezilla or ~/.filezilla.

You need to press Ctrl+H to show hidden files if necessary.

Then open filezilla.xml using a text editor.

Remove the Last local directory tag.

Save the file again and reopen filezilla.

This works for me every time.
