Hello,
I have an important odt file that I can't open anymore, I get the error " Read error. Format error discovered in the file in sub-document content.xml at 296.13(row,col). "
I've tried to fix it using the tutorial on this page https://forum.openoffice.org/en/forum/viewtopic.php?f=7&t=1532 without success.
Any help is welcomed since this is a really important document.
The file has been updated here : https://ufile.io/qdm87
Thanks !
