Cron Issues WHMCS 7.1

[Criot]

Hi,

 

I've contacted WHMCS support but this is an urgent issue which I need to resolve - The first response from them was a predefined reply linking to an article which was very much useless as i've already done it all, not had a peep out of them since in nearly 12 hours. I know that's not incredibly long, but with a serious issue like this it is a long time.

 

The WHMCS cron is no longer running, running it myself via browser returns a 500 internal server error, enabling show errors in WHMCS just make it load a white page but it's still not run.

 

I've tried running it via command line:

Starting (Time: 0.21 Memory: 13.58)
Running Pre-Cron Hooks (Time: 0.04 Memory: 13.69)
Starting Updating Currency Exchange Rates (Time: 0 Memory: 13.7)
- Done (Time: 0.02 Memory: 13.
Starting Updating Product Pricing for Current Exchange Rates (Time: 0 Memory: 13.
- Done (Time: -0.25 Memory: 14.28)
Starting Generating Invoices (Time: 0 Memory: 14.28)
Starting Applying Late Fees (Time: 0.09 Memory: 14.52)

 

Running it with '-vvv' returns nothing either:

Starting
Running Pre-Cron Hooks
Starting Updating Currency Exchange Rates
- Done
Starting Updating Product Pricing for Current Exchange Rates
- Done
Starting Generating Invoices
Starting Applying Late Fees

 

I've seen a few other threads on this forum with the same problem, but their resolutions hasn't worked for me. Anyone else had the issue and know any possible solutions?
