Hi,
are you using w2l 0.9.2? If so, then it's odd, because w2lCore
shouldn't even be loaded when a page is saved. There might be a memory
limit, which is too low. 64 MB should be a good starting point.
Another possibility might be, that there is a incompatibility with MW 1.14.
But my guess would be a too low memory limit.
Hope this helps. If not, you'd have to wait some days, as I plan to
release the next version in the next few days and chances are, that
this bug is fixed by some changes I made.
Best regards,
