OK, this is a weird one. On this one laptop, the flybmi.com website doesn't work properly. The site loads but if I click on the OK button to accept cookies, nothing happens. I can select the departure and arrival airports, but the date selector does not work. No other site that I have tried has any problems, just this one. I have tried the flybmi website on other computers and it works perfectly fine in all of them. The same fault exists when using Mozilla Firefox and Google Chrome. However it works fine with Internet Explorer. So far I have tried the following:
Disabling all add-ons and extensions
Virus scan with Malware Bytes (nothing found)
Uninstalling Chrome and Firefox and reinstalling them
Running CCleaner to clear all cache, cookies, temp data etc. Also cleaned the registry.
Disabling all startup programs using msconfig
Uninstalling all not needed programs
I'm very confused by this problem. I don't know what else to try. It definitely seems to be an issue with this particular computer, and something that affects both Chrome and Firefox, but not IE. Any ideas?
