How to Add Custom PHP Snippet?
1. Please go to your FTP/CPanel, and go to folder "wp-content/plugins"
2. Create a new PHP there and name it with "bp-custom.php". If you already have it, no need to create again. Just open it
3. Paste the snippet on the page and save
PS: On a single "bp-custom.php" file, you only can add one PHP tag code only where it put on the most top of file
If you want to add multiple snippets, please copy the snippet only.
If you don't want to use "bp-custom.php" file, you can use third-party plugin
