One more problem with this on the registration form… if something is filled out incorrectly and the form reloads with an error message, then we’re back to square 1 with the issue I previously described. The form shows a “Please solve Captcha correctly” message, but the Captcha itself is not loaded.
Nevermind, figured it out per the instructions at https://buddydev.com/docs/buddypress-ajax-registration/overriding-modal-styles-from-theme/
Still have no idea where it was previously pulling the template text from, since I *thought* I changed every instance of it anywhere on my server, but whatever, this works now. Thanks anyway!
