Re: Warning on trying External Linking Posted by Pat VDV 28 Jul 2004 09:40 GMT-0000 posts: 224 How did you upgrade from 1.7x to 1.8x? Did you do a clean installation of the Tiki files or did you just copy the new version of the files over the old ones? In my Tiki 1.8.3 I see no reference on line 4175 in tikilib.php to a 'strstr' function. Regards, Pat.
