Hi Rashida!
The page has the issue visible now - 2 screenhots of how it looked are below:

Probably I have to clarify what I did - so you can recreate the problem / find a solution. I was working on the Instagram Gallery addon implementation, which I could not implement because of an SSL (local) error at my hosting provider, who did not want to help.
I helped myself with a little bit of research and some use of AI and found a solution. I had to modify the ./administrator/components/com_sppagebuilder/assets/vendor/facebook/graph-sdk/src/Facebook/HttpClients/FacebookCurlHttpClient.php in one (1) line --> that the cacert.pem file is called.
After that I managed to get past the OAuth of Facebook (Meta) and received the Access Token and Instagram ID. While doing this, the site was acting normal and nothing was wrong.
But the next problem was, that both fields in the SP Page Builder were greyed out. Because of that and based on the information, provided on the internet, I added the Access Token and Instagram ID to System / Setup / Global Configuration / SP Page Builder Pro. After applying this change, the Instagram Gallery addon was working, but the styling of the page went away (in most cases and on most pages). Additionaly my custom added color: #dc143c disappeared in the presets (libraries) + the orange colour, used in the template (the primary one) is also missing. I just have a bunch of blacks and whites - nothing else.
Above that, you can also see, that the part with the band members (left name, center image, right description) in now missaligned - bigger margins / padding.
I reverted the problem with deleting the MySQL DB and restoring a previous (2 or 3 days old" backup od the DB - which indicates, that there may be a problem with the DB - after changing the above things.
Best regards!
