Templates are generally not automatically modified. If you are worried that the upgrade will modify the template, you can export the current template first and then install it after the upgrade. The specific steps are as follows:

Log on to the backstage of the forum. Log in to the forum with the administrator account, and click "Management Center" in the upper right corner to open the background of the forum.

Log in to the background and click the "Interface" button at the top.

Click the interface, and then click the "Style Management" button on the left.

Click Export to export the corresponding template.

Upgrade forum.

Repeat step 1-3 again, and then click Import to enter the installation page.

At this time, the program will automatically download the installation template and wait for the automatic installation of the program to be completed.

After the automatic installation is completed, the program will automatically jump to the style management page. We will select the newly installed template as the default template, and then click Submit.

After prompting that the interface scheme is updated, we will return to the forum foreground to refresh, and the forum template has been updated successfully.
