View Removed Items: ResearchGate often has an "Archived" or "Removed Items" section. Locate this section on your profile page. The exact wording may vary, but it's typically in the "Publications" or "Research" section.
Restore the Articles: In the "Archived" or "Removed Items" section, you should see the articles that were removed. There should be an option to "Restore" or "Unarchive" the articles. Click on this option for each article you want to recover.
Review Your Profile: After restoring the articles, review your profile to confirm that they are back in your list of publications.
If you're unable to locate the "Archived" or "Removed Items" section on your profile, the process for restoring removed articles may vary depending on updates and changes to ResearchGate's interface. In that case, I recommend contacting ResearchGate's support or customer service for specific guidance on how to restore the removed articles.
Additionally, if you have any browser extensions or settings that might affect your ResearchGate experience, it's a good idea to disable them temporarily to ensure they are not interfering with the restoration process.
