Thread: vBCredits II & xCache

This isn't a very easy "bug" to explain, but I'll try my best.

I have the Lite versions of both vB Optimise and vBCredits II, and they run fine for the most part. The only problem I've encountered is after a period of time the credits on my forum disappear. I don't believe it's a conflict with any other mod because they show up perfectly fine for hours at a time, then disappear and eventually come back later on. I've figured out that when they do disappear, if I "Flush Cache" for vB Optimise they come back as if they were never gone.

I'm not talking about missing credits, or not getting what I earned, etc, but the actual display of credits is what's disappearing randomly. Also, when they aren't visible, under "Multiple Currency Information" in the AdminCP they also disappear. I only have 1 currency, which is the default currency from upgrading from the old vB3 mod. Just so I can add as much detail as possible, the transaction page at credits.php also doesn't display correctly, transactions are blank and it doesn't display any credits there either.

I customized 2 template edits to use custom hooks and templates to display credits in a custom dropdown, but I'm pretty sure it still had the problem before that, and it's still an issue since the other pages also mess up.

Postbit example after Flushing Cache:

If it matters, I'm using xCache.

Does this affect other addons, especially ones that use template hooks? Can you give a screenshot of the multiple currency integration page and credits.php transaction pages during the bug? Almost sounds like a datastore issue at that point, but can't imagine how it would have blanks vs flat out crashing, and those two don't have anything to do with template hooks.

As I was typing a reply saying that I'd get them as soon as it happened again.. It started acting up again. This time I also noticed an error on the credits.php page.

Warning: Invalid argument supplied for foreach() in [path]/credits.php on line 188

And I made a mistake earlier, the currency shows in the Multiple Currency Integration page, but when I click Events, and also when I click Activity Amounts Configuration & Automatic Template Edits.. They redirect to the "Create New Currency" form..

After flushing the cache, everything on the AdminCP side returns to normal.


Edit: And no, it only effects this modification.

does it happen within a set period of time? To verify, can you try disabling vboptimize long enough to verify if it doesnt die after the usual interval? are you using a different method for datastore other than the database?

I'll disable vB Optimise for now, and I haven't figured out exactly how long between working and not working, etc. I'm using xCache as the datastore type in vBulletins config.php, aswell as in the vB Optimise settings.

Edit: Actually, I'll just disable the datastore option for vB Optimise for now. If that fixes the error happening, then I'm okay with leaving that disabled. If it still happens though, I'll disable vB Optimise completely and get back to you on that. =)

There's no cache whitelist, but I do know for a fact that such issues could occur if you're using vBulletin's vB_Datastore_XCache class in config.php. If so, try commenting it out.

Yeah I'm saying that when using vBOptimise, using the config.php class is not recommended.

I'm sorry for the delay in getting back to this thread, I've been dealing with some out of control server issues, so I wasn't able to monitor this properly to try and determine more information.

I do have an update though. It turns out, this error occurs regardless of having vBOptimise enabled or disabled. So I'm pretty sure I got it wrong for it being a vBOptimise conflict..

After disabling vBOptimise, the error still occurs. I use the xCache datastore option with my forum, in config.php, and when the error last occured.. I checked into the xCache administration page to look up the vbcredits var data entry, and this is what's displayed:

And this is what it is after clearing the cache (via xCache and not vBOptimise):

The reason I thought it had to do with vBOptimise, was because I was using the Flush Cache option to empty the cache.. What I didn't realize, was that flushed the entire var data cache, and not just what was being used by vBOptimise.

I'm really stumped on this, and I use xCache in place of my database to help performance, I can't disable that.

Thanks again for any help =)
