I have problem running REST API with Query Monitor plugin

There is a problem running REST API when Query Monitor plugin is actve, please deactivate it as it causes a Fatal error in both REST API Explorer or API itself :

PHP Fatal error:  Uncaught Error: Class 'QM_Component' not found in .../wp-content/plugins/query-monitor/classes/Util.php:312 

Only REST API is affected by Query Monitor, all the other part of DyaPress code is running correctly. REST API is using Restler whihc scan all the code loaded which may causes this error.

Privacy notice

As of Dolibarr, all your data are stored on your WordPress database.

Please note that DyaPress UUID are unique and are generated by a call to DyaPress Premium Microservice. DyaPress will check if you have a Premium licence activated and will not propose the “Upgrade to Premium” link in such case.

API URL is registered in our service to ease installation of upcoming Premium version : you only need to configure a DyaPress Premium plugin with the UUID and DOLAPIKEY, so that if API URL is modified, no modification has to be done to your configuration. No other data are sent. Note that API URL can be modified easily as a random permalink is generated on installation and can be changed at any time. This permalink is used as a prefix for the Dolibarr REST API URL.
