J2.5.20, VM 2.6.6
My client has been happily adding new products. All of a sudden, adding any new products cause the product admin page to break after Save. Only the top menu appears on the left of the page, and that product listing below, with no styling. There is no head/body/css/js output, the html just starts in the middle of the page.
All other backend functions & views in VM still work, even the table of products, until I sort by decreasing ID to include the latest product. Then it breaks same as above. Back will take me to the previous page, which displays properly.
I've removed the products 3 times with phpMyAdmin, and re-tested. I thought there might be a broken image, but not 3 times. And they faithfully use Paste as Text in JCK editor to strip extra badness.
I have installed new components & modules recently, but only for the front end and they could create products afterwards. Their hosting isn't running out of space or file count. Nothing is obvious in the access or error logs.
Any thoughts or pointers? Also, is there a debug/log for just the VM backend?
in your log/ or logs/ folder should be a com_virtuemart.log.php if the error is logged
does the broken layout stay till you remove the offending product?
Is it repeatable? i.e. put the same product back and it breaks again?
There are 3.5K errors in the log file, but none seem to be related to any of the product skus/ids that broke during creation. They 100% look like:
ERROR vmError: related product is missing, maybe unpublished [sku] [name] id: [id]
The broken layout does remain until I remove the product. Either by refreshing the broken page, or going back to the products list and sorting/searching by anything that will include that new product on the list. It is repeatable, not by adding that same product, but trying to add any new product.
However... PEBKAC: the user found some gorgeous hi-res photos from their vendor, and was uploading 4-10MB 6K x 4.5K jpg's! Taught them to re-size, and all's well.
