Sorry, I can't provide that right now, because both the production and test sites are running in a high-security environment.
However, I learned more about the problem after foolishly risking a trial on a production site. I had been able to successfully upgrade a test site from TML 3.6.6 to 3.6.8 using the "Fix 2" steps further above and thought I could do the same with a production site. However, that process not only didn't work, it made it impossible to either log in or out. Logout attempts displayed an "Are you Sure" message. Login attempts displayed a "Lost Password" link that didn't work.
Whether TML was activated or deactivated the WordPress admin "Pages" list had "Login," "Log Out," "Lost Password," "Register," "Reset Password," and "Your Profile" pages that could not be displayed or deleted from within the WordPress admin system.
I checked wp_posts in the mysql database and found multple posts with each of those names that each had the post_type "page." I deactivated TML, deleted all those pages directly from wp_posts, and also deleted TML from wp_options. I then installed TLM 3.6.8 in the hope that it would recreate whatever was needed for a fresh installation. That didn't work. Login attempts resulted in 404 "Page not Found" errors.
Reinstalling TML did not re-create any pages in wp_posts (should it have?), so I created them manually with a post_type "Page" and content [theme-my-login]. That enabled login via TML. It also enabled display of the TML logout page when trying to logout. However, logout does not actually occur.
Do you have a script that will delete everything from the mysql database that any version of TML ever created to enable a virgin TML installation, because TML 3.6.8 works with a fresh WordPress installation?
