activating ACP Hides "Advanced Category Excluder" addin from left sidebar list
We apologize for late response. We’re sorry that it cases any inconvenience, we just back from vacation.
There are two ways in order fix the issue you mentioned, you need to open the
“Advanced Content Pagination Pro” plugin’s “acp.php” file 43th string and change this:
add_action('admin_menu', array(&$this, 'add_plugin_options_page'));
add_action('admin_menu', array(&$this, 'add_plugin_options_page'),-1);
Or, open the “Advanced Category Excluder” plugin’s “advanced-category-excluder.php” file, 504th string and make this changes:
Thank you for using our services.
Just found the problem. The Advanced Content Pagination Pro works fine and this problem comes from other plugin.
We spent about two days and found, that the "Advanced Category Excluder" plugin also doesn't have any relation to this issue. This problem comes from "WP E-Signature Signer Input Fields" plugin. It use TinyMCE filter hooks without setting priority and makes a lot of conflicts with other plugin icons, not only with ACP.
The problem in this file: esig-signer-input-fields/admin/esig-sif-admin.php
In this code:
add_filter( "mce_external_plugins", array($this, "sif_add_buttons") ); add_filter( 'mce_buttons', array($this, 'sif_register_buttons') );
As you understand we don't support third party problems, however we added small change in this code and all works fine now. But this change will be lost once you update this plugin in future.
