When I create a new profile in Solspace Importer and I'm asked to upload a file, I get a white page when clicking the continue button.
This is the case for XML, JSON, CSV files.
I have error logging set to 1, but I'm not getting any errors related to Importer. I have the memory limit set to 128M but have tried more. I can see that Importer is writing to the cache dir. I'm running EE 2.8.1, Importer 2.2.5, PHP 5.5.10 on MAMP.
