After working all night (it's nearly 3AM!) in a translation I have to deliver tomorrow, my odt target file won't open, instead I get this error message (in Spanish, sorry):
Error de formato descubierto en el archivo en el subdocumento content.xml en
I've tried validate tags but it is not working (I deleted a tag on purpose
If you mean that there's a tag in a source segment that you have removed in the target segment, that's the origin of your error.
and it did nothing)
"Validate tags" means you must use the function until it says "No tag errors detected" (No se detectaron errores de etiqueta).
It will not correct the errors for you.
How can I recover the file without damage?
By correcting the tag error, and creating the target document error.
