We apologise sleepybear91. Although some emailing systems have been fixed, in order to achieve it, some redundant 3rd party support software was removed and vBulletin update appear to have had universal side-effects across the forum. You are not the only member having these issues. We are trying to sort out these problems.
"Gateway Closed" or "Gateway time-out" Error code 504 are due to server time-outs AFAIK. Like us, the hardware is not getting any younger.
Still have major issues to sort out so you will need to be patient with us. Again we apologise for the confusing and headache kind of forum behaviour you see at times.
