We're currently experiencing issues related with the Contacts API,
Please be patient as we await resolution to the current issues plaguing the API, "Contacts API" is mainly related to the Users & Directory modules of gPanel. However could cause intermittent issues with things such as reports that are running/changing contact information on Users. We currently do not have an ETA at this time but will update once we do, thank you for your patience and continued business.
As always you can contact us via Support@promevo.com for additional questions and/or issues, Thank you!
