Dedecms Modify document Blank page resolution

I encountered the problem is that the release of the content is not a problem, but edit the document, modify the software is a blank page, after the search, as long as the following changes are OK.
Find dede/(is your background login directory, if not modified by default is Dede directory), find the file archives_do.php tutorial file, search header, in line 33 can see

The code is as follows	Copy Code
Header ("location:{$gurl}?aid= $aid");

We modify this here to JS calls like

The code is as follows	Copy Code
echo "<script language= ' web effects ' >window.location.href= ' {$gurl}?aid={$aid} ' </script> ';

As for what reason not to use the header function, let's take a look at the properties of the header. Header (), if the previous output of a space, blank line, any character, will cause header () jump invalidation ....
Because catalog_do.php has called too many PHP files, you may have previously modified the file with the ad, so there is a problem.
