First of all, my php.ini at max_filesize is set more than 10 MB.
I can upload something by PHP if it don't take more than 10 MB of space.
"Then, where is the problem?" When I go to "Import" and select WordPress (XML File), I see: "Maximum size: 2m". My XML file has 5 MB.
I try to upload it, but it says that is too big. How I can fix it?
