At the same time, I received a 500 error if the path was specified: / legacy
First, for some reason there was no slash after the domain name!
Secondly, the domain name specified before the installation may not need to be specified in the RewriteBase rule?
I changed RewriteBase domain.comlegacy to RewriteBase /legacy and my site started working.
Is this really an installation error and did I fix it correctly, or is the problem something else?
