I get a error in config

WARNING: …/plugins/SEO/Metric/Alexa.php(40): Warning - DOMDocument::loadHTML(): Unexpected end tag : div in Entity, line: 793 - Matomo 4.2.1 - (Module: SEO, Action: getRank, In CLI mode: false)


The SEO plugin works by parsing some websites, which might break if they don’t allow your webserver to access them.
So if you don’t need the SEO widget, the easiest thing is to disable the SEO plugin.
