I manage a site for children in Hebrew. The site is already 10 years old and I build and manage it by myself, using an old, now obsolete program. The homepage is an HTM with about 3000 links to a data base of pdf documents. Lately I received complaints, probably from mobile computers visitors, saying that the site appears in gibberish. What can be done to correct this. I add often new documents to the base and I wouldn’t like to change the working program to which I am used. Please advise. Thanks
