I updated today suse and then I stopped running filezilla
filezilla: relocation error: filezilla: symbol _ZNK8wxWindow7IsShownEv, version WXU_3.1 not defined in file libwx_gtk2u_core-suse.so.2 with link time reference
What updates did you install from where?
wxGTK 3.1 (to which your error message points) is not included in 13.2.
You might have some mixture between 2.8 and 3.1 in your wxGTK packages.
And which version of filezilla did you install from where?
Try to switch filezilla to the version in the standard repos.
Or do a full system switch to the repo where you installed filezilla from.
For further help, please post your repo list:
zypper lr -d
