It could be your forum software. When I first started looking at this site, I could access it from my desktop pc using Win10. From my Android tablet, using chrome, I would always get this message:
-----------------------------------------------------------
NET::ERR_CERT_Authority_INVALID
The website's SSL certificate cannot be verified
-----------------------------------------------------------
Chrome would tell me that the site is not secure and I must exit immediately, or the world will end for me. This website is absolutely the only place where I have ever encountered this error message.
If I brought up this site on my phone, whenever I tried to click a link on the main menu, my phone blew out the page and said something like, "This connection aborted. This site could be harmful to your device."
Now, I suppose due to software updates, I can access VHT on my phone and on my tablet without getting those messages. However, I don't use my phone or tablet to access this site because the structure is just too funky to use. On Win10, it works pretty well. I suppose if I installed Tapatalk on my phone and tablet, it might work, but I don't need that for any other motorcycle forum that I use.
