Conflict with Bulk Plugin Activation Using TGMPA

I am facing a conflict when trying to bulk activate plugins using the TGMPA (TGM Plugin Activation) library. I have a total of 10 plugins that need to be installed and activated. Here’s the problem:

1. When I select and activate all plugins except the CFF (Calculated Fields Form) plugin, everything works fine.
2. However, when I select all plugins including the CFF plugin for bulk activation, the following error occurs:

Warning: Cannot modify header information - headers already sent by (output started at C:\xampp\htdocs\vc\wp-includes\script-loader.php:2938) in C:\xampp\htdocs\vc\wp-includes\pluggable.php on line 1435 Warning: Cannot modify header information - headers already sent by (output started at C:\xampp\htdocs\vc\wp-includes\script-loader.php:2938) in C:\xampp\htdocs\vc\wp-includes\pluggable.php on line 1438

This conflict only happens when the CFF plugin is included in the bulk activation. The error does not occur if the CFF plugin is excluded.

Steps to Reproduce:

1. Go to the TGMPA interface and select all required plugins (including the CFF plugin).
2. Click the “Bulk Activate” button.
3. The activation process fails, and the above error is displayed.

Observations:

• The conflict seems to originate from the CFF plugin, as it only happens when this plugin is part of the bulk activation process.
• The error indicates that headers are being sent prematurely, which might be due to unexpected output or whitespace in the CFF plugin files.

I believe the CFF plugin may be causing unexpected output or a conflict during the bulk activation process.

Thank you in advance for your assistance!
