Invoice themes suddenly not functioning correctly

I have been using manager, with the same custom invoice template for years.
Suddenly my template is changed and there is no way to change it back.
The “Accounts” column suddenly appears and then there is too little space for the description making my simple invoice 5 pages long. The majority of the links in the forum on this matter is broken and it seems I now need to learn to code, in order to use an accounting program.
Is there a template generator we can use? How do I get my theme back to working like it did a couple days ago?

That is simply not possible. The obsolete custom themes still function in the latest versions as long as they have been assigned to an existing business as you did before. Just ensure that the desired custom theme is selected in the invoice edit screen.

It is very much the reality, and without coding knowledge there is no way for me to edit it.
You are welcome to send me your email address and I will send you screenshots to show you how it is simply possible.

This is a forum where others like me try to help you. You can anonimize screenshots using an image editor but have to share these on the forum. I asked for edit screens but you are not doing so. You do not even tell us if you still have a assigned the custom theme you used or if it even assists in settings.

It is interesting to note that you feel that developing your custom theme did not require any knowledge of programming as it is written in English which many found cumbersome.

I had the same problem. I went to “Non-inventory items” in “Settings” and made item names. (Example - Contract labor, Hourly, Per Case). Using “Item” column kept the account column from printing.This is the only way I found to keep the “account column” from printing on the invoices. Someone much more experienced than I may be able to give you better advice, but this worked for me. Hope this helps.
