I also had problems entering the forum. This lasted 2-3 days. This happens very often when on holidays a very large number of users try to visit the forum at the same time.
Its OK now. I go to the forum without any problems. Only now it is much faster. Also, forum topics and photos will open faster. Definitely that the forum began to work much better and faster. I know how hard it is to do it. I myself recently due to the lack of free space on the hosting transferred my site to another hosting where there is a lot of free space for the site to work.
Robert, you had a great update on the forum and a full backup of such a huge amount of forum data.
I congratulate you on a job well done.
Thank.
Ruslan
