So, it appears that this is now solved. For my case it was a setting that was thrown out of whack during the process of updating from the free to the premium version. I’m not sure if the problem is actually related to WPE or not, but in any case it’s solved.
For those that wind up here looking for a solution and happen to have the same issue I did I’ll add the following.
Export your wp_wfconfig table and search for wafDisabled.
Mine originally looked like this:
‘wafDisabled’, 0x31, ‘no’
After updating the table it looked like this:
‘wafDisabled’, 0x30, ‘no’
To update the value run the following SQL statement:
update wp_wfconfig set val = ‘0’ where name = ‘wafDisabled’ ;
