504 Gateway Time-out
WHOA, SERVICE UNAVAILABLE!
Hey, speedy surfer, looks like all the demands overwhelmed me. Hopefully I will be ready in no-time!
Or even a total connection refused:
Unable to connect
Firefox can’t establish a connection to the server at forum.mikrotik.com.
The site could be temporarily unavailable or too busy. Try again in a few moments.
If you are unable to load any pages, check your computer’s network connection.
If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.
Also it keeps logging me out at random times.
I understand that these issues will be ironed out but at the moment this forum is not very usable with these kinds of errors.
But the worst of all (for me) is that the prosilver theme is gone.
The current theme might look good at first glance but it's not usable. Usability is more important than flat large monochrome buttons and modern design.
There's a reason phpBB ships with prosilver and not with slickthemes-dead-domain.co theme
With this theme I cannot find anything. I don't know which post is new on a given thread (thus continue reading from where I left last time). Prosilver had orange icons next to each unread reply on a thread.
Also I don't know on which threads I have posted my self (no icon indication in threads list as in prosilver).
The colors (or lack thereof) are a pain to the eyes.
Black text on white background. Great! Makes a nice contrast, perfect for the eyes! Just like the good old 90s
In one phrase: You've just downgraded the forum by removing prosilver..
I know most users out there did not use prosilver so you won't really care about what I have to say but nontheless I'll say it.
Please bring prosilver back otherwise I can't see myself using this forum much anymore. I cannot use a service that makes to want to pull my hair out each time I try to find or read something.
I understand that this is a community forum and I don't (or anyone else) really have a say to how you run it, but I just had to express my disappointment. I don't care about the technical problems. Those can be solved in time. But removing a useful theme in favor of a bad theme is not a technical issue but an arbitrary decision. I really hope you revert that decision.
PS: It took me a few retries to finaly be able to post this reply. The errors I got are mentioned in the beginning of this reply.
PS2: It took 49 seconds for the post to complete. So it's worse than even before as I mentioned a few times here: viewtopic.php?f=2&t=110841#p622022
