We have Artio SEF 2.1 installed on our development server & seen no problems. We went live with the new site yesterday evening & after a few hours every page loaded was covered in dozens of identical PHP error messages like this

Warning: array_keys(): The first argument should be an array in /home7/nigel/webs/www.amb-cotedazur.com/htdocs/components/com_sef/sef.cache.php on line 1

I went into the Artio SEF configuraton & used the 'Clean Cache' button which cured the problem. A few hours elapsed & then we saw the same errors again & again it was cured by hitting the 'Clean Cache' button. After a few more hours the problem recurred & this time I disabled Artio SEF since then we have had no more problems.

It appears this problem is related to either the time elapsed or the number of hits that our site has received but it is not very busy at the moment (under 100 hits per hour).

I really would like to use this component as it produces very nice URLs especially with Mosets Tree directories but clearly I cannot until this problem is fixed. What can we do to help find the cause of this problem?

Hi Nigel,

I think it should be sufficient to switch only the Cache off in JoomSEF's configuration, not the whole JoomSEF.
If you are willing to help us with this problem, try turning JoomSEF with cache on and when the problem appears, send us the /components/com_sef/cache/cache.php file.

Regards,
David

I have actually re-enabled everything & we have had no recurrence of the problem. I do like the product & as the whole site worked OK except for the warning message I was prepared to suppress all PHP error messages if necessary. After reading the help a little more I spent some time making sure that modules that SEF didn't make nice URLs for. Whether that fixed the problem or not I don't know but if it recurrs then I will grab the file for you to look at.

Cheers

Nigel
