I ran into the same problem today. I have a PressBooks site with about a dozen technical webbooks, some of them have equations (rendered with WP QuickLaTeX). Everything has been working fine for over a year. However, when I added some additional pages, the equations in the new pages would not render, and I got the same error. Curiously, all the equations in the existing pages still rendered fine. (I assume they are cached.) I tried various workarounds but none worked until I deactivated WP QuickLaTex and then activated it again. That fixed the problem. You might give this a try. Good luck.

The download history is available in the free version of the plugin.

I experienced the same problem. My download history stopped recording after I updated to version 3.1.12. I rolled back to version 3.1.11 and the download history is recording again.

Hi Diabolo, I have a follow up, related question. I hope it is OK to append on this Topic. I decided users should not be able to change their email addresses. The only two items that users are allowed to do are: change password and delete account. What would be a good way to implement this? On the Account page, there are the links to “Change Password” and “Delete Account”. Nothing else can be changed, yet there is still a “Update Account” button, which doesn’t do anything. Are my requirements too trivial for the Ultimate Member plugin?

Wonderful!!! That does the job. Thank you very much.
