Fatal error on plugin activation

Hello,
After downloading latest version of S2member, when i try to activate it i get this error

Warning: require_once(DIR/composer/autoload_real.php) [function.require-once]: failed to open stream: No such file or directory in /home1/dazza/public_html/precisionweb.design/wp-content/plugins/s2member/src/vendor/autoload.php on line 5

Fatal error: require_once() [function.require]: Failed opening required ‘DIR/composer/autoload_real.php’ (include_path=’.:/opt/php52/lib/php’) in /home1/dazza/public_html/precisionweb.design/wp-content/plugins/s2member/src/vendor/autoload.php on line 5

I checked with s2member server scanner and all my configuration coming green. Please let me know what is causing this. It was working before but after recent update, it is causing that problem.

Thanks
Nazmur

May be a problem with installation. Try to upload the plugin by FTP, manually.

We already tried by uploading it manually. But still getting same error.

Got same problem. Note, that some directories at /wp-content/plugins/s2member/src/vendor are set with uppercase names. Set them to lowercase and the problem will be fixed. No idea why, that corps up at some servers…

i checked but not seeing any uppercase file names. also still getting error

i enabled php 5.6 in my server and looks like plugin working fine now.
