Background: I have three Themeco X licenses. Two are for websites that are part of a WordPress Multisite (WPMS), and one is just a standard WP site (i.e. not part of a WPMS). All three websites are hosted on the same server and have been operating for over a year. This is the first time the following problem has occurred.
Problem: The two WPMS websites now have connection issues (note, the standard site does not have connection issues). The error occurred when I attempted to update Cornerstone on one of the WPMS websites. The update failed, and I received the following error message.
Update Failed: X is not validated. Validate X to enable automatic updates.
I went to X Addons > Product Validation and verified an API key was already entered. Then I verified this matched what's listed under my licenses (https://theme.co/apex/licenses). Finally, I copy/pasted the correct code listed under my licenses and clicked Update API Key, but I received the following error message.
Could not establish connection. For assistance, please start by reviewing our article on troubleshooting connection issues.
I repeated these steps on the second WPMS website. The same errors occurred.
I logged into the standard website and updated X and Cornerstone with no issue.
I contacted our developer, and he went through each of the points listed under Connection Issues (https://theme.co/apex/forum/t/troubleshooting-validation-connection-issues/201). The error does not appear to be occurring because of settings on our end.
Since the standard site has no connection issues, is it possible this issue is due to Themeco X/Pro updates and WPMS compatibility?
Please advise and thank you for your help on this matter.
