Not sure if the problem is just the version or if the upgrade somehow 'fixes' the file. Seems a bit strange that none of the 2019.1 files have had any problems and we have quite a few of them... Re: API Internal Server Error (500) since late last night HiOMS, I am still waiting for my client to update their file. I have confirmed that are definatley also on 2018.3 where all our other clients are on 2019.1. Will let you know as soon as I get feeback from them that they have updated and I can test. Re: API Internal Server Error (500) since late last night Thanks for the updateIan4101will give that a go! Re: API Internal Server Error (500) since late last night We are having the same issue, seems to be only one file also, all other files continue work work as before.
