XF 1.5 Receiving No Upgrade Available


I am currently upgrading from 1.1.4 but receiving "No Upgrade Available" after uploading files of upload folder. I have done it twice, not sure where things are going wrong?

Please help.

Either you have uploaded the files to the wrong location or server caching is preventing the new files from being served.
well i have uploaded files in same location where previous installation was installed. I can see new files there using FTP, how can i get rid of server caching or should i remove internal_data/install-lock.php file?

Do not remove install-lock.php unless you intend on reinstalling (and removing all data). I don't think you want that.

If you're positive the files are uploaded in the correct location -- overwriting the old files -- then it will be the PHP opcode cache not refreshing on file changes. Restarting the web server/PHP-FPM should clear that up.
