I have created an Acymailing Subscription Form module for Joomla 3.9 and successfully loaded it into a Joomla article. I now wish to restyle some aspects of the form, so I have used the Form CSS Class feature in the Advanced tab. I make my adjustments to custom.css. That all seems to work quite well. I will make one change at the beginning of my work and it happens immediately when I save the css and refresh the browser page, but then later changes are not displayed - or if they are, it is 5 minutes or 15 minutes later (after I've googled a few more forum pages trying to work out what's happening). So, eventually my changes get through, but it's not a practical way to work.
I have read all about different cache settings, and I have turned caching off every way I know how. I have adjusted the .htaccess file, an Apache file, I have tested it on different computers, with my hosting service and in Dreamweaver with Localhost and Liveview. Simple text and HTML changes appear immediately, CSS changes take a lot of time - so I must be missing something.
I am wondering if there is something in the Acy module - maybe in top_compresssion_css.php that is interrupting things? Am I posting my changes to the wrong css stylesheet - even though custom.css is working sometimes!
I'm not an expert, so I possibly haven't asked this question quite the correct way - and it's really aimed at the Acyba programmers as the standard answers for caching have not worked for me. I don't mind spending hours and hours trying to fix these things because I learn lots of other stuff as well, but this has now got me beaten! Help!
