Login wp-admin, go to “BM PageBuilder” on left bar, Paste the key.
Note: if there is not the option, please go to themeforest download the Air theme, find :/air-theme/functions/plugins/bm-pagebuilder.zip, login wp-admin of your WordPress, re-install the BM PageBuilder(remove the old BM Pagebuilder firslty)
It will not remove the content built by BM Pagebuilder already.
Be safe, still suggest you make backup(install a backup plugin to do it) before removing any things.
ps:I checked your wp-admin, there is “BM PageBuilder” on left bar, it isn’t necessary to re-install the BM Pagebuilder.
I was able to generate the Google Maps API key, pasted the key into the BM PageBuilder Google Maps API Key location and saved it, refreshed the page to see if it took, and it did. I then went to the contact page and am having the same issue, any help?
