Possible new problem. Something i have not seen before.

Hello,

I am using 1.5.6c with php 7.4. Site has been working fine since my last post. Lost of customers. This morning i noticed admin moving kinda slow. First i tried on a different connection. but still the same. Customers could place orders just fine. The i looked in the cache folder in root and noticed 3 new files that got made earlier today.

I have never had them in that folder. As you can see from the time stamps they are. I have another zencart install and it doesn't have those files in the cache folder in root. I can't even copy them over and delete them. It gives a

Response: 250 CWD command successful
Error: Critical file transfer error

Why are these here now ? And is this the reason for the slow down ?

Just thought i should add , they come back. even if i delete them.

and i now feel dumb. All this time i thought i was looking in my log file folder. Thats why i had never seen them before. Doesn't explain the slow down on the site backend. But still.

Do you, by chance, have SQL caching enabled in one or both of the site's configure.php files?

/**
 * This is an advanced setting to determine whether you want to cache SQL queries.
 * Options are 'none' (which is the default) and 'file' and 'database'.
 */
define('SQL_CACHE_METHOD', 'none');

zencart 1.5.8
php.8.1.2

I too all of a sudden am experiencing slowness in the admin. I am even getting it on my local site.
I am not sure what is causing this issue but today is the fist time I have experience this.

My fronted works perfectly....

I have this set as define('SQL_CACHE_METHOD', 'none');

I did some test on my local site. I have disabled all plugins and my admin is still slow.
I do not get the SQL files mentioned above so i don't think cache is my issue.

have you checked the key:

SHOW_VERSION_UPDATE_IN_HEADER

i would have that set to false.

Ver. 1.5.8a
php 7.4

We too had this problem as of yesterday Nov. 11. even got an error message once across the top where the check is.

Considered the error logs cache and was about to have a dig. However,

Turning

SHOW_VERSION_UPDATE_IN_HEADER

to **false **has fixed it.

(easiest way for regular folk:
go to Configuration -> My Store -> Show if version update available;
then Set to False.

Thank you carlwhat! Big help.

have you checked the key:

SHOW_VERSION_UPDATE_IN_HEADER

i would have that set to false.

I already had this set to false.

Strange that I never had an issue like this but all of a sudden there are multiple people with same issue

There might have been a problem with the Zen Cart version server yesterday; I'd seen a slowdown on one of the sites that I manage, but was trying to do other things.

The issue appears (?) to have resolved itself, is anyone still having the slowdown?

Woke up this morning and all seems good. If I see any slowness ill let you know.

As of 345pm EST the slowness in the admin is happening again. At least we now know its the zencart-version server.

previously you said you had set the key listed above to false. if that is set to false, there is no slowdown associated with the zen-cart version server.

if the key is false, and your admin is still slow, it is something else...

Seeing this on multiple sites across multiple versions, all with update check disabled.

For those having issues please respond with:

1. The Zen Cart version in use, as the version-server endpoint has changed over the years.
2. Any plugins you might have installed, since some of them (like older versions of Sitemap XML) run that version check on every admin page load.

Note: It'll also help to search for plugin_version_check_for_updates (using Tools :: Developers Tool Kit) to see what modules are making those calls.

Great shout. On a site running Sitemap XML 3.9.7, disabling (commenting out) that check immediately restores the performance.

Oddly enough, the sites I saw this problem on yesterday are working fine now with no changes.

My issue is very random. Sometimes back-end is super fast. And other times it is super slow as of 11/13
