#2737 

``/species/c_elegans/gene/WBGene00017578#6--10``
UnderBest BLASTP matches of Homology widget, click on View full blastp list

Previously, the full blastp list wasn't displayed if loading from cache.

**Note: you would need to enable caching using CouchDB from your wormbase_local.conf**, relevant settings can be found within the wormbase_production.conf**

Thanks :)
