Regarding a similar question I only found the advice to delete a table in the database but because I don't like fiddling with the db very much I like to ask: Are there ways to force craft to generate all transformations for all assets/images?
There is such a function in ExpressionEngine in the CP and I try to replicate this behaviour. I also installed the ImageOptimize plugin for that reason but no luck with that also.
thank you very much!
