A meilisearchconfig.xml different from the one provided with the extension was detected.

It is recommended to use the meilisearchconfig.xml file shipping with the Meilisearch for TYPO3 extension as it provides an optimized setup for the use of Meilisearch with TYPO3. A difference can occur when you update the TYPO3 extension, but forget to update the meilisearchconfig.xml file on the Meilisearch server. The Meilisearch configuration sometimes changes to accommodate changes or new features in Apache Meilisearch. Also make sure to restart the Tomcat server after updating meilisearchconfig.xml.

Your Meilisearch server is currently using a Meilisearch configuration file named {f:if(condition:meilisearch.meilisearchconfigName, then:meilisearch.meilisearchconfigName, else:'not set')}, the recommended schema is called {recommendedVersion}. You can find the recommended meilisearchconfig.xml file in the extension's resources folder: EXT:meilisearch/Resources/Private/Meilisearch/. While you're at it, please check whether you're using the current schema.xml file, too.
