RE: Is there any way of doing a bulk delete from the database after downloading a csv file then reloading the file with some details amended. The problem with this is that if entries are uploaded without deletion they will appear twice. Also if a file is downloaded then reinstalled is it possible to keep the same ID number in the database for SEO as this is what is indexed by GOOGLE. It may be rare for this to be necessary but it may happen.
Export the directory using the CSV Export All tool on the Connections : Tools admin page. Make your changes and import the updated file. The entries will be updated vs duplicated.
I recommend enabling beta support for the CSV Import extension on the Connections : Settings admin page under the Beta Version tab. After you do you’ll be able to install the beta version of CSV Import which has improved import performance for large CSV files and greatly improved user feedback of the import process.
RE: I have followed the tutorial and installed the Google Maps API keys apparently successfully but with the maps do not appear in my listings although set to be shown.The “Show Map” text is there and opens the window but no content, same in both views.
I suspect there is still an issue with your Google Maps API key. Open the page in Chrome, hit the F12 key and then click the Console tab. Google will show you error messages related to their API which can help you figure out the issue.
Hope this helps, let me know what you learn!
