Title: Plugin doesn’t recognize ACF Pro Last modified: March 12, 2025 --- # Plugin doesn’t recognize ACF Pro * [behu6338](https://wordpress.org/support/users/behu6338/) * (@behu6338) * [1 year, 3 months ago](https://wordpress.org/support/topic/plugin-doesnt-recognize-acf-pro/) * **Hello,** I have the Acymailing plugin installed on a WordPress site, using the free version. I want to use the ACF addon to retrieve custom post elements in newsletters. I have ACF Pro installed. * However, when I try to install the addon, I get a message saying that ACF must be installed. It seems like it doesn’t recognize ACF Pro… Do I need to have both the free and Pro versions of ACF installed? That seems odd. * Or is there another way to make the Acymailing addon recognize ACF Pro? * Thanks in advance!

We assumed that their paid version worked like most other plugins (a main free plugin on the store, and an additional paid plugin that extends the free plugin’s features). * If the paid version of ACF doesn’t work like that and rather replaces the free version (i.e the free version doesn’t need to be installed), could you give me its main folder name in wp-content/plugins/ ? Could you also give me the name of the main file in this folder? It should start with a block like this one: * ```wp-block-code installed = $this->installed || acym_isExtensionActive('advanced-custom-fields-pro/acf.php'); ``` * In the file **wp-content/plugins/acymailing/back/dynamics/post/plugin.php**, replace the line 596 by: * ```wp-block-code $installed = acym_isExtensionActive('advanced-custom-fields/acf.php'); $installed = $installed || acym_isExtensionActive('advanced-custom-fields-pro/acf.php'); if (!$installed || !function_exists('acf_get_field_groups')) { ``` * This should accept the pro version of the ACF plugin when testing if it is installed. * Thread Starter [behu6338](https://wordpress.org/support/users/behu6338/) * (@behu6338) * [1 year, 2 months ago](https://wordpress.org/support/topic/plugin-doesnt-recognize-acf-pro/#post-18361865) * It’s strange (but a good news), when I’ve try to reinstall the plugin “AcyMailing integration for Advanced Custom Fields (ACF)” just now, it worked well (I didn’t modify the files yet as you ask in your last message). I did updates today, but can’t remember what plugins :/ Did you release an update for AcyMailing ? * [jeremyacy](https://wordpress.org/support/users/jeremyacy/) * (@jeremyacy) * [1 year, 2 months ago](https://wordpress.org/support/topic/plugin-doesnt-recognize-acf-pro/#post-18365937) * We indeed released the v10.1.4, but it doesn’t include the modifications I listed in this thread. * Thread Starter [behu6338](https://wordpress.org/support/users/behu6338/) * (@behu6338) * [1 year, 2 months ago](https://wordpress.org/support/topic/plugin-doesnt-recognize-acf-pro/#post-18367710) * Hi, Indeed, I was able to install the ACF add-on, but I cannot use it. When I go to the plugin settings, it indicates that the plugin is not installed.I’ve inserted the two code snippets you provided, but this has triggered a critical error on the site. Attached is a screenshot of the modified code in the file acymailing/back/dynamics/post/plugin.php. Perhaps I made a mistake while inserting it? * Additionally, there’s something odd: at line 7, the { is highlighted in red. Could this be related ? * ![](https://i0.wp.com/www.mjc-herbasse.fr/wp-content/uploads/2025/03/code-plugin- acymailing.png?ssl=1) * Thanks, Best regards * [jeremyacy](https://wordpress.org/support/users/jeremyacy/) * (@jeremyacy) * [1 year, 2 months ago](https://wordpress.org/support/topic/plugin-doesnt-recognize-acf-pro/#post-18367901) * There is a syntax error, maybe we didn’t have the same version of the plugin. You can replace the line 597: * ```wp-block-code if (!$installed || !function_exists('acf_get_field_groups')) { ``` * By this: * ```wp-block-code if (!$installed || !function_exists('acf_get_field_groups')) { return;} ``` * Thread Starter [behu6338](https://wordpress.org/support/users/behu6338/) * (@behu6338) * [1 year, 2 months ago](https://wordpress.org/support/topic/plugin-doesnt-recognize-acf-pro/#post-18368001) * Hi, I replaced the line 597 by the new one ; there’s no critical error anymore, but still can’t use the ACF addon.I share you the screenshot of the code of the file plugins/acymailing-integration-for-acf/plugin.php.Maybe there’s a syntax error too ? * ![](https://i0.wp.com/www.mjc-herbasse.fr/wp-content/uploads/2025/03/code-plugin- acf-acymailing.png?ssl=1) * Do you want a temporary admin access to my WordPress interface ?

Is it correct ?Thanks * [jeremyacy](https://wordpress.org/support/users/jeremyacy/) * (@jeremyacy) * [1 year, 2 months ago](https://wordpress.org/support/topic/plugin-doesnt-recognize-acf-pro/#post-18369757) * The code you showed seems to be correct, there is no syntax error. * Could you send the ACF pro package to us with our contact form so that I could do some tests on our test sites?
