AALayer Posted January 4, 2021 Share Posted January 4, 2021 This seems to be a common issue for some hosting providers. Wait for some WHMCS reply. 0 Quote Link to comment Share on other sites More sharing options...
xyzulu Posted January 4, 2021 Share Posted January 4, 2021 Just do a manual upgrade.. it's quite simple https://docs.whmcs.com/Updating#Performing_a_Manual_Update 0 Quote Link to comment Share on other sites More sharing options...
Sanin Posted January 5, 2021 Author Share Posted January 5, 2021 Hello, Thank you for reply. Problem isn't on server side, problem is in upgrade to WHMCS 8.1 if you are using WHMCS from version older than 6... Problem with template.

xyzulu Posted January 5, 2021 Share Posted January 5, 2021 Quote Fatal error: Maximum execution time of 300 seconds exceeded That is a serverside issue. Please try the manual update.. it might just work and save you lots of time. 0 Quote Link to comment Share on other sites More sharing options...
Sanin Posted January 5, 2021 Author Share Posted January 5, 2021 In my previous post you can find resolution. It's not server side issue, you can reach execution time to ... unlimited but WHMCS 8.1 will never open. 🙂 This topic can be closed. Thank you. 0 Quote Link to comment Share on other sites More sharing options...
WHMCS Support Manager WHMCS John Posted January 7, 2021 WHMCS Support Manager Share Posted January 7, 2021 Hi all, We have been able to determine that this issue may occur when an order form template contains a theme.yaml file referencing itself as the parent theme. To resolve it, ensure that any custom order form templates in place don't reference themselves as the parent theme inside the /templates/orderforms/$custom_theme_name/theme.yaml file. For proper usage of the theme.yaml file in order form templates, please refer to https://developers.whmcs.com/themes/order-form-templates/ Please let me know if that is the case here. 0 Quote Link to comment Share on other sites More sharing options...
