I was able to successfully install UNA all over again and after doing that, this is the webpage that is displayed.
Thanks in advance!
Hello onisokien !
As we discussed together due to with this your topic https://una.io/page/view-discussion?id=8031 you already solved this problem.
As we discussed earlier, I explained that I will try installing a new instance of Una on my server. Everything worked fine (Installation and Setup) but when I tried to access other pages like Studio Launcher, it displays the same error as last time.
