Permalink Chaos

Hello together,

I’m pretty new to WP and my installation is now runngin for around 1 month. Since back then I try to change my permalinks to have the postnames instead of the standard but this isn’t working.
I take a look at my installation and saw that it is able to write and change the htaccess file. When I do a changement in the config a new file of the htaccess is created and it normally should work but it doesn’t.

I thought that this maybe a special problem, since I’ve installed my WP on a Western Digital MyCloud. So I searched the internet for a month now and it seems that none o the gien solution is working for me.

Is there something I have overseen? Is somebody ese using it’s NAS for a WP blog?
Does anyone has a clou?

thank you very much
Michael

PS: I never create a new topic if I was not searching the web long enough to be sure that I have overseen a solution. So please do not call me a “noob” or something, I’ve tried my very best 😉
