Thanks both. I did try a default theme and that seemed to clear up the issue so now I have to consider if its worth it to reformat everything to match a new theme as it came over messy.
@wodobo has this Yoast plugin continued to work? To me it seems like a patch I am worried it won’t fix the problem. Going to try it but having the same issue.
Thank you @tobiasbg , love the plugin! So this solution did remove the warning box but it still has a spinning wheel and greyed out Elementor “elements” window. I thought it may be Elementor but this was occuriring with the error message and someone else identified similar issues here: https://ww.wp.xz.cn/support/topic/elements-grayed-out-and-progress-wheel-is-turning-for-ever/
Thanks for your assistance.
