magento 1.9 – Simple configurable product extension errors

I have used the SCP extension of Organic Internet for a while and it has always served me well. However, nowadays, when I run the price indexer, the maximum and minimum prices of simple products are no longer being recovered.

Along with this, when I enter a configurable product and look at the associated products section, the products are displayed as expected, however, the titles of the products are missing. When I disable the SCP extension, the titles of the products reappear.

I am running magento 1.9.3.3 with SCP 0.8.2, any help would be much appreciated.
