Solution to blank page in Discuz Forum x3.1

I found the reason why the page was blank today, probably because of the compatibility problem of the php version, so this is only the case for some users. Let's share it here.

The cause of the code in the sourcefunctionfunction_core.php file is as follows:

The code is as follows:	Copy code
Static $ replacements = array (":", "@", "&", "=", "+", "$ ",",","/","? "," % "," # "," [","] ");

Replace all double quotes with single quotes.

In x3.1, a function is added to the sourcefunctionfunction_core.php file:

The code is as follows:	Copy code
Function fixurl ($ url ){ Static $ fix = array ('% 3A', '% 40',' % 26', '% 3D', '% 2B', '% 24 ', '% 2C', '% 2F', '% 3f',' % 25', '% 23',' % 5B ',' % 5D '); Static $ replacements = array (":", "@", "&", "=", "+", "$ ",",","/","? "," % "," # "," [","] "); Return str_replace ($ fix, $ replacements, urlencode ($ url )); }

The red part of the code appears. Replace the double quotation marks with single quotation marks to solve the problem:

The code is as follows:	Copy code
Static $ replacements = array (':', '@', '&', '=', '+', '$ ',',','/','? ',' % ',' # ',' [','] ');
