Ormandj -- What you are describing we have seen in the Pacific Northwest. It was a breakdown/stagnation of the signal path BEFORE is reached Sucuri, our firewall system. The error was caused by problems at GTT.net BEFORE it reached Sucuri and before the signal even got to our server. Not much we can do to fix that. As I have explained, it is like we have an open door at our store, but the road to the parking lot is obstructed.
Again, for the 50th time folks, please 1) try another browser; 2) Go to your browser settings, typically "privacy and security". Look at the clearance options. You need to clear:
A. Cache (all time)
B. History (all time)
C. Site Downloads
D. Site Cookies
You may also have to set your browser security setting to allow the site to set cookies. Unfortunately, the browser folks are evolving site security stuff almost on a weekly basis and there is no information provided to site owners. Firefox, for example, regularly makes changes that screw up site formats and we just have to guess the reasons why.
