# Site Health Issues & PHP legacy code

 * Contactic is causing some issues to show up in the new WordPress feature “Site
   Health”. When this plugin (or Contact Form DB, to be clear) are active, the following
   two critical errors appear:
 * _The REST API encountered an error
    Your site could not complete a loopback request
 * Additionally, under the “Recommended Improvement” section:
 * _Background updates may not be working properly.
    – Could not confirm that the
   wp\_version\_check() filter is available.
 * These do not appear on other sites using the same hosting / config and on this
   test site when Contactic / Contact Form DB are not installed and/or disabled.
   The issues seem directly related to the plugin.
 * Additionally, the PHP Compatibility Checker plugin for v7.2 finds many issues
   with Contactic, which I’ve pasted below, with a PATH redaction. I realize that
   some of the mysqli related warnings could be due to backward compatibility code.

 * Hi,
    thank you for your feedback, mysql related messages are indeed due to backward
   compatibility code, it’s not executed when mysqli is available so no error will
   really happen. We work on the other issues I’ll keep you informed.
