Follow up: I think I figured out what might be going on, although that doesn’t explain the wrong file names.
Weaver Xtreme Plus Version 1.3 is long obsolete, and probably won’t run with the latest Weaver Xtreme Version 3.1 or the Weaver Xtreme Theme Support plugin 3.0.
You apparently did not update your Xtreme Plus plugin. The latest version of the Xtreme Plus plugin is 3.0.1.
Weaver Xtreme Plus Version 2.1.4 will work with Weaver Xtreme 3.1, but does not support the newest features. Weaver Xtreme Plus Version 2.1.4 was issued before any licenses expired, but the licensing system does allow anyone with an expired license to download anything.
If you can provide your license code to me via e-mail (weaver at weavertheme.com), I will e-mail you the last version of Weaver Xtreme Plus that was available before your license expired.
But to use the latest version of Weaver Xtreme (3.1.3) and the Weaver Xtreme Support Plugin (Version 3.1), you need at least Weaver Xtreme Plus 2.1. It is really important to use the latest version of Weaver Xtreme.
