I'm trying to install Channel Images on my EE 3.3 site. The install says:
Within the /system/expressionengine/third_party/ directory, copy the channel_images folder into your sites ./system/expressionengine/third_party/ directory.
Within the /themes/third_party/ directory, copy the channel_images folder into your sites./themes/third_party/ directory.
Go to the Modules area in the ExpressionEngine control panel, find Channel Images in the list, and click Install.
But my back end is not organized that way. In fact, I can find no folders for "third_party." I tried to intuit where the add-on was supposed to be installed, and indeed after doing it I could activate the addon within my site's addon manager.
However, after activating it, I cannot create any new fields. I get the following error:
Error: Unable to load the requested language file: language/english/channel_images_lang.php
What can I do?
