Hello, PJone,
Thank you for contacting us.
We would like to assure you that updating the theme typically does not lead to any issues. However, to assist you effectively, could you please capture a video of the actions you are taking and the problem that occurs?
Also, please read this article from Eleemntor plugin – https://elementor.com/help/publish-update-button-not-work/
Additionally, we recommend that you request your hosting provider to supply the server error log and to review the situation from their end.
Once you have this information, please share it with us so we can further investigate and resolve the issue.
Best Regards,
8Theme’s Team
