After installing new opencart theme by "themeburn" site traffic increased. Most of traffic generated by empty user agent.
Looking logs I found out the sourse of requests with empty user agent :
168.1.75.14 - - [11/Mar/2018:07:08:31 -0500] "GET /image/cache/tb/main.b32853840deeea469a0caceda1189373.css HTTP/1.0" 200 571763 "-" "-"
This ip is my site's one, so i can't just block it using htaccess. All requests from my ip with empty user agent are similar and they all request this main.css.
Is this situation normal and its just theme feature, or i should search for a problem?
