Hey guys,

I hope you can help me. We wanted to migrate our server and switching from Plesk to a self managed webserver.

Now we have the following problem: mod_rewrite is activated and working for the first layer of urls (/login, /forums, /blogs, etc.). All deeper layers won't work e.g. the link to a thread or subforum etc. Those sites cannot be found by the suite (Error code: 1S160/2).
Could somebody point out what could cause this problem?

Server config:

• OS: Ubuntu 18.04
• PHP: 7.3
• Database: MySQL 15.2 (using readline 5.2)
• Webserver: Apache 2.4.37
• AllowOverride is set to All
• .htaccess is working (checked as we use AuthBasic and the first layers work)

Thanks in advance,
Phil

PHP 7.3 is not supported for Invision Community 4.3.6. It will be supported in 4.4. Till then you will need to downgrade to PHP 7.2

Oh shoot.. if this really is the problem I could punch myself. Thanks for pointing that out, I hope this is causing the problem as it would be the most easiest fix. I didn't think of that as all requirements during the installation have been green (I guess IPS is checking for a version value higher than defined).

Will report back with the result.

Yes, PHP 7.3 will cause the error you are mentioning.
