It fails with 403 value.

I think if I am getting 403 there is something wrong here and it is not being me or something with my connection. I used to use this plugin without any problems.

PS: it seems to be a problem with API key, but I don't recall using a key , and it used to work just out of the box.

I test the condition to occur 403.

• Custom API Key doesn't use -> 200 or 429( Status 429 #47 )
• Invalid API Key -> 400
• Correct API Key but It has API connection issue -> 403

Try this:
"Settings" -> "Google API Settings" -> click "API Check" in "Status Check" (output dialog is "API Key exist" or "API Key does not exist")
If the output is API Key exist, "Save Key" in "Set API Key" with blank textarea. (if you don't use custom API Key)
if not... I can't reproduced. I need more information about condition.

It says "key doesn't exist" . It is possible it is being an issue with my connection then.. I attached the folder for plugin for you to see, guess it is the best option

thank you. unfortunately, the files didn't meaningful data because it is same build file by latest. so I only say reinstall it once if it is not usable.
currently, the error is occured? if so, I recommend to use custom api key(if you know the usage). if not so, the error is flaky (it may be api rate limit by shared API)
