That plugin didn’t work for me, I got an error (maybe due to my cache plugin). Anyway, I found another one that actually showed me all the transient files, and there was a whopper of a file (tons of mumbo jumbo) attached to my instagram plugin. So I deleted that one transient file manually and bam it worked. Thank you. And here’s the link to that other plugin for future reference: https://ww.wp.xz.cn/plugins/transients-manager/
