Problem: If you're experiencing issues with accessing pages with URLs containing special characters (such as Arabic, Russian, Chinese, Hindi, etc.) and you're using the All-In-One Security (AIOS) plugin, the problem might be due to the 'Advanced Character String Filter' setting. Solution: We recommend disabling the 'Advanced Character String Filter' in the AIOS plugin to resolve this issue. Here are the steps to follow: 1. Go to the WP Security plugin. 2. Navigate to the 'Firewall' menu item. 3. Click on the 'PHP Rules' tab. 4. Select 'String Filtering'. 5. Ensure that the 'Advanced Character String Filter' is disabled.
If this solution does not resolve your issue, or if it seems outdated or not applicable to your case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins.
