We recommend Google Chrome or Firefox Web Browsers on all operating systems and devices for the best experience.

If you are already using Chrome or Firefox please try the following steps in the order given and stop when the issue is resolved.
 
Please ensure that cookies are allowed to be set by the web browser.
 
  • Re-boot:

If you are using a laptop and routinely allow it to 'sleep', please perform a full power down re-boot.

Similarly, if you use a desktop and never turn it off, please perform a full power down re-boot.
 
  • Update the Operating System:

Using, as appropriate, the Windows/MAC/iOS/Linux Update function, check for updates to the operating system. If there are any, you will likely be prompted to re-boot.
 
  • Update your web browser (instructions below):

Chrome:

Click on Customize and Control Google Chrome (which may appear as three vertical  dots at the top right of your browser).

In the drop-down menu:
Select Help > About Google Chrome. 

This will check that your version is up to date, and install any outstanding updates.  
Restarting Chrome will be required if updates are installed.

Firefox:

Access the Menu via the three horizontal lines at the top right of your browser.  (Or select from the menu bar - if shown)

On the Menu select Help > About Firefox.  

This will check that your version is up to date, and install any outstanding updates.  
Restarting Firefox will be required if updates are installed.
 
  • Clear your web browser cache (This will delete cookies and some 'remembered' information)

Chrome:

In the drop-down menu:

Select More Tools, and then click Clear Browsing Data.

At the top of the Clear browsing data window you will see “Obliterate the following items from.” 

In the drop-down box, select “the beginning of time”.

Check the boxes next to Cookies and other site and plugin data, and Cached images and files. 

When checked, click Clear browsing data.

Re-start Chrome.

Firefox:

In the menu, or having selected Tools from the Menu bar (if shown), select Options.

In the new window that loads, select Privacy from the left side of the menu.

In the middle of the page, see the section titled History.

In that section, there is a sentence: “You may want to clear your recent history, or remove individual cookies.”

Click the “clear your recent history” link and a new dialog box will appear.

In the Clear All History box, set the time range to clear to Everything.

Ensure the boxes underneath Details ‘Cookies’ and Cache’ are selected. 

When checked, select the Clear Now button.

Re-start Firefox.

If none of this works, please email support@ovitraders.com for further help.
