error: pictures don’t show

All 9 pictures on this page https://www.ecocom.dk/fotogalleri/ have disappeared as I would upload a new image… You can’t see the pictures, but still the links ind the (missing) pictures are still working.. Almost same problem on this page: https://www.ecocom.dk/kontakt/ : When uploading af very small picture, I get this error (look at page).. When removing the picture, the problem is solved.. But that mean, that I can’t upload pictures to the page.. This code-mess is shown on the page: “[vcvSingleImage class=”vce-single-image” data-width=”85″ data-height=”85″ src=”https://www.ecocom.dk/wp-content/uploads/2017/10/ikon-tlf.gif” data-img-src=”https://www.ecocom.dk/wp-content/uploads/2017/10/ikon-tlf.gif” alt=”” title=”ikon-tlf”]” It happened after updating wp-softare or plugins.. Have removed the plugins again, but it didn’t solve the problem..
