Each time I make any major modifications to my webpages, I copy and re-name the most recent project so that, if something goes wrong, I have a back-up. I have two projects at the moment, each with its own copy, amd all four have the same horizontal and vertical tabs/guidelines.
While working on a new page on my most recent project, my tabs have all but disappeared and those that remain are in the wrong places. I opened the older projects in the hope that the tabs would be correct in at least one of them, but they are just the same as in the current project. Is there any way to restore them all without laboriously re-setting them manually, please? There are so many that the task is daunting, to say the least.
