Cannot modify header information

Hey there,

Sorry for the late reply here! Hope you are safe and well.

According to our developers, there are few reasons for that warning, most notable of which are theme/plugin using “echo” and whitespaces before/after PHP opening/closing tags. Also, if echo, printf, var_dump or other output is used that could lead to such notification.

In detail the reasons are explained here: https://stackoverflow.com/a/8028987

You can use the following articles with the help of your developer to find exact code that is responsible for the error:
