We have an attacker who’s been hitting us pretty hard in the afternoons for the last four or five days. John’s having a devil of a time permanently blocking him/them.
I like that explanation better. In that case you will get a handle on it. I wish you could identify him also but that doesn’t seem likely.
There's software to fix this issue. I finally decided to spend some time today researching this since FR was no longer working well enough to use it. If you like I can do it again and compile a list of software fixes for this.
As I said in another post though; it really is time to hire a professional software company to redo the entire site with formatting options, like buttons, and drop down menu's like any other website newer than 20 years old. In other words; make it usable again. MIUA! I don't understand the reluctance to do this.
