“All of my tables and queries are stored on the shared drive mapped .. ” i don’t understand how TABLES can be stored there. Tables are stored by the MySQL server . And SQLyog newer reads table files. It simply queries the MySQL server.
if a mapped drive is available for the OS/Wndows, it also is available for SQLyog. There is no change in SQLylog 12.1 causing any changed behavior here. I also verified for myself that I can use a mapped drive with SQLyog 12.1 (shared from another Windows machine on the network (not webdrive.com, but it simply does not matter: if Windows exposes a shared drive to SQLyog with a drive letter, SQLyog sees it as a local drive).
Are you sure that there was not an outage of misconfiguration?
