It most likely is human error... I have no doubt.
I was working with someone who was previously working on the site and had played around with using the sidebar in the blog template to display the portfolio page and then I subsequently asked for the sidebar to be removed from the blog page so that all that would show would be blog posts. This was done and for a while it worked.
Since then I have started working on the site by myself but I have less knowledge of the coding etc. On updating the blog page (I want to use instead as a news page- no change in the way that I set up posts etc but just change in what it's called) I added posts as usual - it looks fine in the cms part of the site but when I make it live it shifts the position of all the posts to 3 columns instead of one and keeps incorporating pages from the portfolio page. I have tried downloading the theme from dessign again and copying the code for the blog template and inserting into the template using the editor but it's not registering any changes. I tried switching the code back and the page shows exactly the same no matter what changes I make. I should add here that the changes do appear when I preview the pages in the cms/ back end of the site, the changes just don't appear at all when made live. It just shows the same page again and again.
I have tried emptying the cache of my browser and trying different browsers and the problem is the same. I have also checked for any cache type plugins and I don't have any at all. I am using the free download of the architekt theme so there's no support provided from this side of things. I haven't yet tried reinstalling the theme as I wasn't sure how to go about it and I wouldnt want to lose any info or have to spend time correcting possible errors.
The sidebar was on the right side of the blog page and it was coded to show links to the portfolio. The blog listing would feature on the page in one column. Now what's showing instead is three columns across the page with a mix of blog posts and portfolio pages.
I will try and get a link for you to see. Thanks for your help
