The jsonrpc request:
{"jsonrpc": "2.0", "method": "call", "params": {"xml_ids": ["", "website.option_ripple_effect"]}, "id": 680124702}
response:
{"jsonrpc": "2.0", "id": 680124702, "result": []}
The response should be:
{"jsonrpc": "2.0", "id": 680124702, "result": ["website.option_ripple_effect"]}
I have reinstalled website and updated all modules several times. No change.
For example, trying to change the font or colors does not work. The defaults are kept.
I'm experiencing te same issue. Did you ever find a solution?
In my case, I think some custom module was to blame. I had inherited and extended a theme. But even when I removed it, the problem occasionally appeaed. I didn't really need that functionality though, as I was using my own custom css for color. Ultimately the problem was solved by My solved by moving to 15.
