WordPress was telling me to update my PHP to 7.4 to be able to have the latest security and for the site to run optimally. So, I ran through the procedure to install PHP 7.4 on IIS and activate that version on the IIS server so that it would be used with my WordPress site.<\/p>\n\n\n\n
When I changed the active PHP instance to 7.4 in IIS, my website broke completely and would not load any longer. I decided to revert back to 7.2 while I figured it out. From most of the troubleshooting instructions I saw said to check and disable the plugins. I had more than 20 plugins running which would take WAY too long to test each one. <\/p>\n\n\n\n
I’m like, “There has to be a log with the errors like Event viewer for PHP since it is a PHP error!” After looking through the settings, I found the path to the error log file C:\\Windows\\Temp\\PHP74x54_errors.log<\/em><\/strong><\/p>\n\n\n\n Here is what I found in the log to lead me to the Crayon Syntax Highlighter to be the problem:<\/p>\n\n\n So I started looking on that error and found the following article:<\/p>\n\n\n\n Fix for Crayon Syntax Highlighter WordPress Plugin and PHP 7.3 Fatal Error \u2022 Crunchify<\/strong><\/a><\/p>\n\n\n\n This article talks about Crayon not being updated for a long time and the changes in the PHP code for 7.3.1 and above breaking WordPress websites. I went through the article and repaired the PHP files that were broken and causing the error. There seemed to be four problems in the code. I did find the latest version on Github<\/a> which had all the PHP files that needed changing. Instead of updating the entire plugin, I just updated the PHP files with the current version ones from the Github site. That worked great and my site is back up and running normally.<\/p>\n\n\n\n REFERENCES:<\/em><\/strong> WordPress was telling me to update my PHP to 7.4 to be able to have the latest security and for the site<\/p>\n2021 04:04:24 UTC] PHP Warning: preg_replace(): Compilation failed: invalid range in character class at offset 4 in C:\\inetpub\\YourWebsite\\wp-content\\plugins\\crayon-syntax-highlighter\\crayon_langs.class.php on line 340<\/pre>\n\n\n\n
Thanks again the guys at Crunchify for fixing this issue. I’m sure we will have even more updates when WordPress finally catches up with PHP 8.0!<\/h4>\n\n\n\n
