I assume you have added svg to the FilesMatch file types code. I have very little experience or knowledge about svg files.
<FilesMatch "\.(svg|gif|jpg|jpeg|png|bmp)$">
Not really sure since I don’t have any svg files to test with. Maybe this link below will be of some help. You can confirm or eliminate BPS as the cause of an issue/problem by doing the standard troubleshooting steps, which will allow you to isolate the source of the issue/problem.
