Did you do a backup before running the upgrade? If yes, it might be a good idea to revert to your original site then redo the upgrade but first disable and completely remove Ajaxsearch and make sure you unselect the Ajaxsearch snippet when running the upgrade. If that works fine, you can then manually install the new version of Ajaxsearch.
Good idea. I did take a backup, and restored it when the upgrade didn’t work.
Would be wise to have this problem sorted, as per the link in my original post, I’m not the first one to come across it.
I’m honestly not sure why some people have this error and some don’t. I’ve upgraded a bunch of MODx sites through from 0.9.6.3 to 1.0.5 and never run into this issue before. However, I did incremental upgrades, so when 1.0.0 came out I upgraded to that, then I upgraded to 1.0.2 when it came out, then to 1.0.4 then to 1.0.5, so it wasn’t too much of a jump during upgrades. Not really sure that has anything to do with it. I do remember though that at some point I had to make changes to my AjaxSearch calls when some of the syntax changed, but usually the errors would only show up right where the search box was. I never got the kind of parse errors you’re reporting. So not entirely sure what it is that breaks some sites and not others.
Good luck, let us know how it goes
