Tried again later and got the expected error message due to missing slash in URL.

The log is fine on my RPC. I've uploaded it again with a modified name. Mantis won't let me upload a duplicate file unless I delete the original one first, but I can#t see any way to delete it.

uploading the same corrupt zip does not help me, please can you unpack the zip and re-create it.

The zip is not corrupt on my computer. However I have created and uploaded a fresh one which as far as I can see is identical. If it's getting corrupted then it's getting corrupted somewhere else.

The original URL is in error, it should be https://twitter.com/ljrich/status/443477034744827904

This is OK with 0002652 if JavaScript is disabled, if enabled NetSurf goes onto a seemingly endless "Fetching, Fetching, Processing" loop, log file DJP_log/zip added.

The cited URL renders OK with CI#3046, Iyonix, RISC OS 5.22, with Javascript on. It does take a while.

I suspect that David Pitt's report of 'a seemingly endless "Fetching, Fetching, Processing" loop' is another manifestation of the slow regex interpreter which was fixed recently.
