I changed the template on my site and unfortunately its performance has dropped a lot, in short, it's slow. It would be useful for someone to analyze this problem and implement solutions (e.g. some plugins) that will speed it up, and thus "pass" the Google page speed test. I would also be happy to talk about a possible change of server, if the Expert feels that the current one is not efficient.
In conclusion, I would like my site - menworld.pl to be looked at by someone who actually knows Wordpress and its optimization does not come down to installing one plugin, but rather knows what to check, what to remove, and what to add to actually make the site faster.
