No results on

Hi, I have tried to use this plugin on my website https://www.agfisicos.com, but I have some difficulties, since I can not get results with some shortcodes, like for example: [wpbmb retmax = 400 highlights = “pain, Transcutaneous, TENS” highlights_type = (all fields) AND “electric” [All Fields] AND “nerve” [All Fields] AND “stimulation” (“transcutaneous electric nerve stimulation” “[All Fields]) OR” transcutaneous electric nerve stimulation “[All Fields] OR” tens “[All Fields]) AND (” pain “[MeSH Terms] OR” pain “[All Fields] [wpbmb retmax = 400 highlights = “pain, Transcutaneous, TENS” highlights_type = “background” tags = “pain, TENS”] “transcutaneous electric nerve stimulation” AND (last 30 days) [/ wpbmb].
What am I doing wrong?
Thank you in advance
