Hi starting new thread (pls ignore my earlier response on old thread) - i have the similar symptom - page not loading!!
got lots of access attempts yesterday ( I had to turn off the email notification as my email was beeping every 30 seconds!!
I counted the rows on wfBlocks and there are 2800+ rows, last one was about 2 hours ago.
On JS console error is as follows:
2
Uncaught RangeError: Maximum call stack size exceeded load-scripts.php?c=1&load%5B%5D=jquery-core,jquery-migrate,utils,json2&ver=3.8.1:3
