And There were problems such as uploading and displaying avatars, local mail, and a lot of error messages (PHP Deprecated), However, after I used (bugfix-pupi1985), either by changing some codes or&nbsp;overwrite some files, all the error messages disappeared and the site now works fine.</p> <p style="text-align:left">&nbsp;: But one problem remained which is</p> <p style="text-align:left"><u>PHP Deprecated: mb_strtolower(): Passing null to parameter #1 ($string) of type string is deprecated in /home1/xxxxxx/public_html/xxxxxx/qa-include/util/string.php on line 765)</u></p> <p style="text-align:left">&nbsp;This error appears in the error log after adding an answer, comment, or modification.</p> <p>I will be very grateful and appreciative for your cooperation</p> Q2A Core https://www.question2answer.org/qa/108863/php-8-1-deprecated-error-messages Tue, 20 Jun 2023 19:38:18 +0000
