I suspect someone copied moved files from $HOME to /var/www/html/* 
because user_home_t is no label for /var/www/html

I would propose you to:

# remove your custom module
semodule -u my-httpd

# add a local fcontext to the directory that httpd needs read-write access
semanage fcontext \
   --add \
   --type httpd_sys_rw_content_t
   '/var/www/html/ow_plugins/ow_userfiles/plugins/base/attachment(/.*)?'

# reset all labels to default
restorecon -rv /var/www
