For some people with Acabado they experience issues with being unable to link the sidebar [ About Us ] feature to a post, this appears to be tied to mod_security rules on the server or host.
To resolve this speak to your host about removing the following mod_security rule.
If you see this line in your Error Log “mod_security rule [id “2500182”] at [/opt/apache24/httpd/modsecurity.d/activated_rules/slr_rules.conf:1989] triggered!”, you have to whitelist the rule.
When you want to build landing pages people talk about how you need page builders, the thing is though that Gutenberg by itself may be more than good.
Acabado has SEO functionality baked into the theme which can cause issues when you like to use Yoast, Rank Math, or other SEO plugins.
Jquery within Acabado is disabled by default to maximize page speed, you can enable it with specific plugins that keep changing but include Elementor, etc.
