This does not prevent the plugin from working. * About the “The Warning: Cannot modify header info…” : * This warning indicates that another plugin sent HTTP headers too early, preventing the “Anti Bots” plugin from blocking malicious visits. Headers are used to control redirects, cookies, and caching, and if sent prematurely, they disrupt the normal plugin execution flow. * Why It Happens: * A conflicting plugin or theme outputs data or calls header()/setcookie() too soon. Common culprits include caching, redirection, or optimization plugins.Whitespace or characters before/after PHP tags  can also cause this.Impact: * How to Fix: * Identify the conflicting plugin by deactivating others one by one. Check the theme by switching to a default WordPress theme temporarily.Contact support for the problematic plugin if identified.Please, let me know if that works. * Regards, * Bill * Thread Starter [meylodie](https://wordpress.org/support/users/meylodie/) * (@meylodie) * [8 months, 3 weeks ago](https://wordpress.org/support/topic/generates-warnings-or-errors-with-mod-debug-enabled/#post-18659712) * Hello, thank you for your answer. I tried to deactivate the different plugins, until only Antibot was left, I also renamed “cache” directory to “cache-back” and same for another cache file in the wp-content, using an SFTP client. I didn’t do the theme, because it would be too much work taking notes of all the custom options and restoring them.So far, nothing changed : each time I click to “Save the modifications” in the “General Settings” tab, (with the options “test” and“ 4 weeks”, it redirects from : “*/wp-admin/admin.php?page=settings-anti-bots&tab =general_settings” to : the page “wp-admin/options.php” where the same lines are shown: * > Deprecated: Creation of dynamic property AntibotsWPSettings\OptionPageBuilderTabbed:: > $antibot_tabs is deprecated in /homepages/13/d4298888195/htdocs/citrotux.org/ > htdocs/wp-content/plugins/antibots/settings/page-builders.php on line 179 > Warning: Cannot modify header information – headers already sent by (output > started at /homepages/13/d4298888195/htdocs/citrotux.org/htdocs/wp-content/ > plugins/antibots/settings/page-builders.php:179) in /homepages/13/d4298888195/ > htdocs/citrotux.org/htdocs/wp-includes/functions.php on line 7168 > Warning: Cannot modify header information – headers already sent by (output > started at /homepages/13/d4298888195/htdocs/citrotux.org/htdocs/wp-content/ > plugins/antibots/settings/page-builders.php:179) in /homepages/13/d4298888195/ > htdocs/citrotux.org/htdocs/wp-includes/functions.php on line 7144 > Warning: Cannot modify header information – headers already sent by (output > started at /homepages/13/d4298888195/htdocs/citrotux.org/htdocs/wp-content/ > plugins/antibots/settings/page-builders.php:179) in /homepages/13/d4298888195/ > htdocs/citrotux.org/htdocs/wp-includes/pluggable.php on line 1450 > Warning: Cannot modify header information – headers already sent by (output > started at /homepages/13/d4298888195/htdocs/citrotux.org/htdocs/wp-content/ > plugins/antibots/settings/page-builders.php:179) in /homepages/13/d4298888195/ > htdocs/citrotux.org/htdocs/wp-includes/pluggable.php on line 1453[ * The theme I am using is [https://wordpress.org/themes/chronus/](https://wordpress.org/themes/chronus/).

Do these warnings prevent Antibot from functionning, or do not any of them prevent it from working?

These new rules, in WordPress debug mode,** warn that in the future**, if you update PHP to newer versions, the code **migh**t cause errors.**It’s not urgent** but it’s good to fix everything as soon as possible to avoid future surprises. * I made another change to our plugin to avoid the warning: Deprecated: Creation of dynamic property page-builders.php on line 194 * **Please, update to version 1.62** * Read the log carefully and pass this line to your **theme developer**: * /themes/xxxx/functions.php:323 * Same for the  **GDPR plugin**, which appears to be sending data to the site header prematurely. This may prevent AntiBots from functioning properly, because when it tries to deny access, another plugin has already improperly granted it. * I suggest you familiarize yourself with the tools we recommended before to better handle these problems.
