Import Listings feature stopped working for a while now
I run an existing directory using the current Vantage theme 4.2.7 (just upgraded to 4.2.8).
We currently have more than 54,000 listings, most of which were imported into vantage (using a listings.csv) file when we migrated to vantage.
The problem we have is that for the past 4 weeks, the import listings function has stopped working. We keep getting the message 'imported 0 items'
We have been importing listings successfully before now, hence the listings.csv format is not the issue. It just stopped working. We tried a fresh install but it didn't solve the problem.
What could be the problem?
Does the vantage theme have a maximum number of imported listings?
