I tried installing Instapress into a new wordpress site with a fresh download and I got the following error when I try to activate the plugin:
Warning: require_once(Instagram_XAuth.php) [function.require-once]: failed to open stream: No such file or directory in yourpath/wp-content/plugins/instapress/instagram.php on line 46 Fatal error: require_once() [function.require]: Failed opening required 'Instagram_XAuth.php' (include_path='.: yourpath/wp-content/plugins/instapress/instagram-php-api/:yourpath/wp-content/plugins/instapress/classes/:yourpath/wp-content/plugins/instapress/PowerHour_Geocoder/') in /home/devrep/public_html/site2/wp-content/plugins/instapress/instagram.php on line 46
I looked at an old installation and realized the plugin was missing directories and files. Here’s an archive until they get it fixed.
Download instapress v 1.5.3 here
Instapress is an AWESOME plugin!
