I have a site that throws a critical error when I try to update the options. I made a copy of the site on a different server and the error doesn’t occur. Do you know what might cause this:
Fatal error: Uncaught Error: Call to undefined function ctype_xdigit() in /hermes/bosnacweb05/bosnacweb05/bosnacweb05ce/b936/nf.cudahca/public_html/wp-content/plugins/redux-framework/redux-core/inc/classes/class-redux-colors.php:205 Stack trace: #0 /public_html/wp-content/plugins/redux-framework/redux-core/inc/classes/class-redux-colors.php(287): Redux_Colors::sanitize_hex(‘ffffff’) #1 /public_html/wp-content/plugins/redux-framework/redux-core/inc/validation/color/class-redux-validation-color.php(42): Redux_Colors::sanitize_color(‘#ffffff’) #2 /public_html/wp-content/plugins/redux-framework/redux-core/inc/classes/class-redux-validate.php(39): Redux_Validation_Color->validate() #3 /public_html/wp-content/plugins/redux-framework/redux-core/inc/classes/class-redux-validation.php(197): in /public_html/wp-content/plugins/redux-framework/redux-core/inc/classes/class-redux-colors.php on line 205
Server info:
WordPress version 5.9.5
Current plugin: Template Library and Redux Framework (version 4.3.21)
PHP version 7.4.18
Thanks for any advice.
