After installing the Multiple Store View Pricing extension version 2.3.5 on Magento M188.8.131.52, I got an issue related to reindexing with ForeignKey from table mg_catalog_product_index_group_price_store.
How can you help to fix it?
The reindex issue is caused due to the ForeignKey from the table mg_catalog_product_index_group_price_store.
Since the ForeignKey part is not necessary, so to fix the issue, we have hot-fixed to remove it from our extension. (the Magento default also does not the ForeignKey part).
To remove this part, we have modified this file app/code/local/Bss/MultiStoreViewPricingPriceIndexer/sql/bss_multistoreviewpricingpriceindexer_setup/upgrade-1.0.4-1.0.5.php.
Please check the attachment file to get the changed file and replace it and then flush the cache on the site.
