Hi,
I have got below soft rejection can any one help me to where is my error.
Please make sure that your theme doesn’t raise any PHP errors, notices or warnings. Enabling wp_debug or installing the Debug Bar plugin can help you with this. https://envato.d.pr/82CWvx
You don’t have to find/download any pixelgrade-care plugin.
The reviewer’s screenshot only shows that the reviewer already has on his WordPress installation a plugin named pixelgrade-care which already uses a version of TGMPA, but your theme (Ojasvi) conflicts with that plugin, by not using TGMPA correctly
You should use a customized version of TGMPA with a text domain, functions prefix, etc - to not generate conflicts with other plugins or builders.
