I said I would not fix it, but I am annoyed by things not working as they should.
As I said before, I changed no settings in the MT4 back end. Everything all of a sudden stopped working. This morning I confirmed this by going through the system activity log. It logs everything being done in this blog. I mean everything. Every comment, trackback, search, post, settings change. Everything. I went through 385 entries, and not one was there any setting changed.
So, now that I know I did not break it by tweaking a setting, I decided to mess with the settings. Can’t get any worse can it?
Nope, I fixed it. I changed it from dynamic archives to static archives (which is what it should have been). Republished and all is normal now. Individual post pages work. Monthly archives work. Comments work. All good.
Now that it is fixed, I do not know if I will switch to WordPress or not. Simply because if I completely redo the blog, I will lose ranking in the SERPs. Plus need to do a lot more work to rebuild. But I still might switch. I want my blog to merge seamlessly with the new site design, so I will need to “investigate” the depth of customization I can do with MT4.x.
Will see in due time.
EDIT: Craptastic system is broken again. Back to the very first problem I had with MT3.x. Comments just don’t work. Choice is made, I will upgrade to WordPress, and suffer and SEO loss that might incur.
