Endless Save Loop with Canonical Rewrite Code

Hi,

below is the code i use for all my sites for canonical issues and so far it's worked ok


However, on my latest site it is refusing to be saved by Modx.

All sites are on the same server and running the same version of Modx Revo 2.5.7

By trial and error I deduced it was the last bit that was causing the problem

And in particular the

So I rewrote it as

Just to see what would happen. It worked ok except I got the id number in the url instead of the alias.

So I changed it to "alias"

That seems to have worked but not sure if it's correct code syntax without the tilde and the extra brackets.

Plus I still don't know why the original code won't save.

Anyone got any ideas?

Thanks

The fact that you have one cached and one uncached site_url tag could be a factor.

You might try the Canonical extra, which injects the canonical tag for you when it's appropriate.
