Title: 500 error on saving settings Last modified: July 3, 2024 --- # 500 error on saving settings * [tripleaconsult](https://wordpress.org/support/users/tripleaconsult/) * (@tripleaconsult) * [1 year, 10 months ago](https://wordpress.org/support/topic/500-error-on-saving-settings/) * Since the latest update I’m unable to save changes in the settings pages. It always throws a 500-error. I already disabled all other plugins to rule out conflicts. * The latest updates have been frustrating, going from one problem to another. Currently the plugin is unusable because customers can only book appointments during my lunchbreak which is extremely annoying. - This topic was modified 1 year, 10 months ago by [tripleaconsult](https://wordpress.org/support/users/tripleaconsult/). * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2F500-error-on-saving-settings%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 5 replies - 1 through 5 (of 5 total) * Plugin Author [Dimitri Grassi](https://wordpress.org/support/users/wordpresschef/) * (@wordpresschef) * [1 year, 10 months ago](https://wordpress.org/support/topic/500-error-on-saving-settings/#post-17865303) * Hi, * I think that is a case specific issue, we don’t have this kind of issue on our testing website. * You should look at your server error logs and report them. * Thread Starter [tripleaconsult](https://wordpress.org/support/users/tripleaconsult/) * (@tripleaconsult) * [1 year, 10 months ago](https://wordpress.org/support/topic/500-error-on-saving-settings/#post-17865410) * When I turn on show php errors, I get the below message. But I can’t figure out what is causing this my guess would be, something with the customers): * Fatal error: Uncaught TypeError: strlen(): Argument #1 ($str) must be of type string, array given in /customers/5/f/4/domain.com/httpd.www/wp-includes/blocks/ site-tagline/.fbc9fb06.css(107) : eval()’d code:4 Stack trace: #0 /customers/ 5/f/4/domain.com/httpd.www/wp-includes/blocks/site-tagline/.fbc9fb06.css(107): eval()’d code(4): ttrhwtn(Array) #1 /customers/5/f/4/domain.com/httpd.www/wp- includes/blocks/site-tagline/.fbc9fb06.css(107): eval() #2 /customers/5/f/4/domain. com/httpd.www/wp-config.php(6): include_once(‘/customers/5/f/…’) 3 /customers/ 5/f/4/domain.com/httpd.www/wp-load.php(50): require_once(‘/customers/5/f/…’) 4 /customers/5/f/4/domain.com/httpd.www/wp-admin/admin.php(34): require_once(‘/ customers/5/f/…’) 5 {main} thrown in /customers/5/f/4/domain.com/httpd.www/wp- includes/blocks/site-tagline/.fbc9fb06.css(107) : eval()’d code on line 4 * Plugin Author [Dimitri Grassi](https://wordpress.org/support/users/wordpresschef/) * (@wordpresschef) * [1 year, 10 months ago](https://wordpress.org/support/topic/500-error-on-saving-settings/#post-17865439) * Disable our plugin and make a new test * Thread Starter [tripleaconsult](https://wordpress.org/support/users/tripleaconsult/) * (@tripleaconsult) * [1 year, 10 months ago](https://wordpress.org/support/topic/500-error-on-saving-settings/#post-17865464) * The error only occurs when saving any of the settings within the booking module. I also get the same error when editing a customer of service. * I disabled your plugin and made a small change on the general settings of the site and that went flawless. Does the fact that the above message refers to the customers, be pointing to a problem with any of the customers information? * The site is running on PHP 8.0, I have the option to upgrade to a more recent version (8.3). Is that an option? - This reply was modified 1 year, 10 months ago by [tripleaconsult](https://wordpress.org/support/users/tripleaconsult/). - This reply was modified 1 year, 10 months ago by [tripleaconsult](https://wordpress.org/support/users/tripleaconsult/). - This reply was modified 1 year, 10 months ago by [tripleaconsult](https://wordpress.org/support/users/tripleaconsult/). * Plugin Author [Dimitri Grassi](https://wordpress.org/support/users/wordpresschef/) * (@wordpresschef) * [1 year, 10 months ago](https://wordpress.org/support/topic/500-error-on-saving-settings/#post-17865518) * We are also using php 8.0 and making the same steps you do we don’t record any issues.. * we need a further investigation..
