I was wrong, Autoptimize seems to be the culprit. Problem is solved: I have excluded styles.css.

Thanks Tijmen. The message in the error log is: FastCGI /…/ aborted: incomplete headers (0 bytes) received from server after 1 sec.

I solved it by adding a short manual. Happy with the result!

It is working again.

Thanks. Is it possible to remove the distances in store listing? It is a bit confusing for short distances.

I have found the open new window and use maps.google.com function. It works, but I would like to show the route on my website.

The distance shown in the display is different from the Google maps distance (shorter). Do you know why?

Google is fickle. Yesterday the first thing to do was improving server response time and reordering css and js (not done yet), today I need to resize images (what I already did).

Thanks, I understand. Both plugins give same results for minification. I have to find another way to further speed up my site.

Thanks, Frank! Now I just have to find which plugin gives the best results.

Now I get a warning: Recently an error occurred while creating the CSS / JS minify cache: No sources to serve.
W3 Total Cache warning has discovered the same issue.

Thanks, Frank. Browsing the site itself gives no errors.

Testing leads to the conclusion that the problem is in the combination of Autoptimize and the W3 Total Cache Minify section. PageSpeed Insights can do its job when I uncheck the HTML minify settings in W3 Total Cache. The other option is to use Total Cache minify, but then I need to uncheck both HTML and JS options in Autoptimize. I am not sure yet which combination gives the best results.

The CSS sections can be combined without errors.

The solution in that thread does not work for my site.

I am already using that option, but the bot still got through. I added in the rewrite rule to my htaccess file and the hits disappeared!

RewriteEngine on
# BEGIN block access for empty user agents – 403 error
RewriteCond %{HTTP_USER_AGENT} ^$
RewriteRule ^(.*)$ – [F,L]
# END block access for empty user agents

I found it here: https://ac2a.com/how-to-block-access-empty-blank-user-agent/

I found a solution for using .htaccess to block empty user_agents. Can I do this without causing other problems?

Thanks for your help, Héctor! It is working fine now.
