at first i was changing the index.php, then, when i checked my site, changes was not displaying, the old version still displaying, so i decided to upload again all the files and check if the changes will displaying, but it doesnt, then i tried also to another computer and smartphones, but still the old version of my site is displaying
Don’t be mad but I have to ask this question
are you 100% sure that you uploaded the modified files to the right address and not to some other htdocs folder?
actually i have 2 subdomains, one is ictapp.free.nf and the other one is guestraffle.rf.gd, and i uploaded my files in their each htdocs, but neither of the two whenever i update the files, it does not update my site,
ictapp seems to be a more advanced version which is almost 100kB larger
Try adding www in front (http://www.ictapp.free.nf/) and visit
maybe it forces your browser to treat it as a new domain and pull new files instead of serving from the cache.
There is another possibility that your PHP file that you want to update exceeds 1MB file size and is rejected by the server and the old one always remains.
