Opencart Admin Issue Maybe Server Related - Manual Orders and Other

Hello guys

I have an issue with me Opencart admin.

I have a server with a couple of websites on including a forum also. I had issues with too many sql connections so asked the provider to look into it. They said them made some changes and used PHP-FPM .

See below quote

Afterwards I tried to add a sale manually on my opencart store in my admin panel, selecting the customer was fine in step 1, but on step 2 when I try to add a product I do the search and auto complete brings up a list of products, when I select a product and click the add option, nothing happens no product is added no matter how I try, also I noticed if upload an image, it uploads but then its not visible to add, if I later go back to it, I can then add the image.

There was also an issue with the journal theme when I added a different product to the carousel , the full journal control disappeared from the admin panel, and through an error on the store how page, I had to go back to my admin modifications option and refresh cache and the journal control re-appeared.

I'm not sure what has happened but everything was fine before the server change, on reverting it back to the previous settings via the server support , I'm still getting the same issue in opencart...

Can anyone shed any help or advice on this, is it some type of Java issue? How can I check or is it an easy fix or something I'm overlooking.

Any help would be appreciated failing that I'm going to have to look at a server restore and manually add any customers/orders back on from before the date.

Many Thanks

Adding onto this I can edit a product then save and then re-visit the product again within the admin and the changes I made have not shown again, although they show on the store front end..Later on they show in the admin.
