Wordpress has been working, then yesterday I noticed updates, did these above and now I can't get to the Wordpress home page ie... 192.168.0.173/wordpress
If I add any other address (ie... 192.168.0.173/wordpress_1) I get a 404 error.
Looking at the LOGs I see that the PHP was upgraded to 7.4 from 7.3
Then I logged into new PHP version and for options (as was going to disable plugins) I found the the links were wrong for site URL & HOME, changed and all ok now
I've fixed/solved my own question, it might be useful for someone else, should they have issue too
