after clean install of oxwall and trying to update photo plugin the source file has been uploaded via FTP.

After this the Dashboard panel and all administrative part are stucked where there is request to upgrade Photo plugin's DB. By pressing the only possible button nothing happen expect presenting error message that page not found.

I really don't know what to do except delete the site but I don't want to do it.

Can you tell me please how to continue OR how to remove the plugin withou using deactivate ( nevertheless it is not working).

Thanks,

marek
