I was very reserved to post this question, but this is something that I am facing in almost every website, and would like to get feedback from others on this. The upload package file in the extensions installer poses an unstable behavior, making the installation a pain.
While trying to install extensions in various server environments, some extensions will be installed without any problem, but for some it won't work right away. It freezes and keep showing the "installation screen" without any progress, if I don't cancel it, it will just stay there forever.
There are many cases, where I have to keep re-trying the installation for several times. Then all of sudden, it will complete the installation without any difficulty and without any delay.
I can't find any common clues for when this is happening, it does not happen for any specific extension nor the size of the extension is related.
There are no permission issues, tmp folder location is defined correctly, no FTP settings - and again: at some point it will manage to install the extension in question without any troubles.
This is very annoying and time consuming while building a website and also not the very best for the customers.
Are you also facing this issue? Anyone has any idea what can be the problem here?
