Hi @yusufdamin,
Can please let me know which kind of plugin gives that error(I mean Custom Plugin or wordpress downloaded plugin).
If you are using custom plugin Please check the all files Below points.
The most common causes are:
1. A white space before or after the PHP opening or closing tags
2. A file encoded in UTF-8
3. Another issue when something is called at the wrong time, or a call that cannot be resolved without intervention
4. Using the WordPress add_option function. Switching to update_option instead can resolve the problem.
I believe it might be the UTF-8 encoding try changing it to ANSI.
