Hey Jesus. Thanks for the note here and sorry that you’re having issues. This is an interesting one and the issue hasn’t come up yet. How are you trying to update – from the backend of your site? Please make sure that you’ve got the PRO license key added as it is required for the update.
Were you able to update The Events Calendar to 2.0.6, and find that just PRO is problematic? If you can give me a rundown of the above I can try to troubleshoot this for you. Thanks for your patience so far.
