I can't believe how many issues have the templates, SPPB with J4 .. is a nightmare, trying to upgrade bring a lot of issues. and even worse in SPPB 4. In this case after install the quickstart of salon template, need to downgrade the php version because your J4 version brings bugs, after fixed my self and upgrade to the latest verision of J4 I can put the PHP8.0 (not the 8.1 have problems also this one) All of this after to clean all the files on my server and DDBB, in order to install a clean new version of J4 (before I had the correct one, but when I install the quickstart, pop up a lots of problems, of this needed to clear all in my server).. At the end I STILL HAVE issues.. (what a nighmare!!) Now the problem when I want to use the pages on SPPB and wait serveal minutes come out the "Internal error 500", so I CAN'T use the SPPB ANd the second error is the slider NOT work! I saw all the solutions, even I replaced with the correct .js .. and nothing.. My question is.. why don't FIX all this problems after all the clients having the same problem, again and again.. and why do no REPLACE the quickstart with a correct WORKING version of the J4 SPPB and template! We paid a lot of money to have all the time issues after issues! FIX it
