Seems the more I work in website development, the less I know. On 12/29/16 I created the subdomainhttp://picsnmore.tanneco.com/ using concrete5 ver. 5.7.5.12 and since then I have uploaded images and such to this virtual gallery on a regular basis. About a month or so ago I started noticing broken image links. Sometimes I would reload every image to a given page. Other times I could login as Admin and republish the page and the problem would resolve itself. About a week ago image links broke again and I started having problems with fonts and page layouts. Then I discovered that the only way the site would load correctly, or reasonably correctly, was by using the URLhttp://tanneco.com/picsnmore/.

After considerable research, I am none the wiser. It looks like in theory a subdomain site should work with either sub.domain.com or domain.com/sub though such appears not to be the case in reality. I can only get the above site to work with the domain.com/sub format. I have another concrete5 site, also ver. 5.7.5.12, in which some of the images and layout work correctly when accessed by http://myecwidstore.tanneco.com/index.php/services... whereas other images and layout only work correctly when accessed byhttp://tanneco.com/myecwidstore/index.php/services... . With the sub.domain.com version, the Title Logo is missing but the Client pictures at the bottom of the page are present. On the domain.com/sub version the Title Logo is present but the Client pictures at the bottom of the page are missing.

Any assistance would be greatly appreciated as I would certainly prefer to stop doing whatever I am doing wrong as opposed to reloading images and such every few weeks. Incidentally I placed a redirect in the htaccess file for the picsnmore site so that anyone using the failed sub.domain.com link would be redirected to the working domain.com./sub version.

Thanks again for your support.
