I am having the same problem. I’ve used Alyeska before with no problem but purchased it again for a client yesterday and it will not work. This is what the host team said to me:
It appears this is being caused by a memory leak from your theme. We’ve tried upping the php memory but it continues to error out. All of the files appear to be in the correct place and pointing to the correct folders. The issue appears to be with your theme.
