We have many forms that looks like this. They were all working until we installed 10.4.5.
The CSS is this
.nameInfo, .idInfo { display: inline-block; } .nameInfo input, .idInfo input { width: 100%; }
After the upgrade only 1 of the dozen or so forms has this problem on archive. I can't understand what why how to even troubleshoot this since there is no interface for previewing an archive.
