I have been skilled in 2 months, I didn't expect to be fuddled day before yesterday. It seems necessary to record it.
First modify the site information:
The main modified file is not a lot, don't forget the site information in /source/admin/admin_function.php and the URL at the bottom of the page.
Then change the display style of the forum:
Download the style from the Internet, upload it to the Archive_in file directory, remember the format of this package is .tar file form. Then enter the manager's background, import the style. Manage style files, set the style you just imported as the default style.
Go to the front desk, ok? what? Nothing at all?
Don't worry, just as I expected. Contrast comparison of the number of files in S1 and several other folders in SKIN, some files are missing in folders generated by the originally imported style. Copy all the files, all override. OK
Go and see, there should be no problem.
