I will give you the Instabuilder 2.0 plugin for your business/marketing needs.
No I do not. Go to your wordpress admin panel, go to plugins, add plugin, upload the .zip and that's it.
go to your site file directory and go to /home/(your cpanel login)/public_html/wp-admin/ (look for the file "php.ini" or make one if you dont have it paste this in there max_execution_time = 180 max_input_time = 600 post_max_size = 128M upload_max_filesize = 256M that should fix it
However many you want. I nulled the plugin. You're free to use it :)
Yeah, I don't know why that happens to some people. Go to the Instabuilder dashboard, then go to the .zip for Instabuilder that i'll send you then extract the templates one by one. Go back to the dashboard and install the templates one by one, that should work!
