This is a bug - please change line 22 of components/com_jevents/helpers/category.php to read

$options['table'] = '#__jevents_vevent';

Thanks for highlighting the issue

After changing error 1054 Unknown column 'i.id' in 'field list'

Can you enable debug and show us the full query? I see you are on Joomla! 3.4.2 so it might be slightly different to our tests.

Thanks
Tony

Where do you see this error arising - its related to counting items in some way but I can't find in Joomla where you would be making this sort of call.

I can see in the code where the error appears - I just can't think what you would be doing in Joomla to make it happen.

it's just a duplicate test site, no problem
if know where the error, write here the result

I'd like to know which Joomla menu item in the backend you have selected?

You could try adding

$options['field'] = 'catid';

at line 23 of the file referred to above as a fix.

add $ options ['field'] = 'catid'; no effect

menu item Manage events
administrator / index.php? option = com_jevents & task = icalevent.list

but the error is also displayed in the frontend

Is it still exactly the same error message?

Can you send me login details via PM so I can take a look?

test site is on a local network not access

I tested some different situations

1) uninstall Jev3.2.15 -> clean directories and DB -> new installation Jev3.2.15 - error
2) transfer of empty tables from functional installation - error
3) clean install J3.4.1 -> update J3.4.2rc -> Installation Jev3.2.15 - OK
4) clean install J3.4.1 -> update J3.4.2rc -> Installation Jev3.2.15 -> transfer of old Jev. data tables - OK
5) another test site (different data and components / same server) update J3.4.2rc, Jev3.2.15 - OK
6) clean install J3.4.1 -> update J3.4.2rc -> Installation Jev3.2.15 -> transfer of complete old J database table - error

the only difference is the addition of DB query from the parent class JCategories

LEFT JOIN `jos_jevents` AS i
   ON i.`id` = c.id
   AND i.state = 1
   AND (i.language = '*' OR i.language = 'en-GB')

error probably relates only to this concrete installation

I will personally deal with migrating data to a clean install (associated with the upgrade server)

Thanks for your help

Is it still exactly the same error message?

the change in the table option value should remove references to the non-existent jos_jevents table

first error Table 'database.jos_jevents' doesn't exist
after add $options['table'] = '#__jevents_vevent'; - show error Unknown column 'i.id' in 'field list'
after add $options['field'] = 'catid'; show error Unknown column 'i.id' in 'field list'
after change to $options['_key'] = 'catid'; show error Unknown Column i.language' in where clause

after application update_package from older versions J3.4.1 is all OK

Thank you for confirming it!!

Hello,

Thanks for help
Oli

I'll upload version 3.1.46 with a workaround in a few minutes - but you should really upgrade to JEvents 3.2.17 as a preferred solution

hi
ok where I can then download the update, so that I need not make any new templates.
thanks for the help

Hello,

For some reason the package hasn't worked correctly.

Geraint is uploading 3.2.18 now.

Please update.

Thanks
