Description:
After installing publisher 1.6.6 (not updating but installing as a new plugin) the following error is displayed in the CP:

"Unable to load the requested file: helpers/low_variables_helper.php"

The following is played on the front end:

Error Number: 1054

Unknown column 'publisher_status' in 'where clause'

SELECT row_id, col_id_4, col_id_5, col_id_39 FROM exp_matrix_data WHERE field_id = 11 AND publisher_status = "open" AND publisher_lang_id = 1 AND entry_id = 21 AND is_draft = 0 ORDER BY row_order ASC LIMIT 100

Filename: third_party/publisher/models/publisher_query.php

Line Number: 110

All Low plugins are using the latest versions (see attached) and did not have any issue until Publisher was installed

Detailed steps to reproduce the issue:
1. Install Publisher 1.6.6
2.
3.

Did you click the run P&T updates link at the bottom of the settings page?

Oh so that happens after/during the install process? Low vars must be triggering something to happen. I’ll try to look into it tonight. I might send you a query to run to fix it later tonight or tomorrow.

So to clarify. Publisher is not installed… You click install, then the very next thing you see is the low variables helper error?

BoldMinded (Brian)

I’ve been looking into Publisher’s code and this doesn’t make any sense. Publisher doesn’t make any references to low_variables except to return early and not run any code if it detects low_variables, which Publisher does not support. Are you 100% that helpers/low_variables_helper.php file exists and is readable? I feel like if this was a broader problem I would have had more reports of it b/c a lot of people use Low Variables.

Edit the publisher_query file and add this conditional.

class Publisher_query
{
    private $cache_key;

    public function modify($find, $replace, $sql, $debug = FALSE)
    {
        // Add this...
        if (ee()->publisher_lib->is_installing()) {
            return $sql;
        }

You’ll need to un-install and re-install. That might fix it, but I still have no explanation as to why there is an error loading a file that is not Publisher’s, which I suspect is what is terminating the install process, thus the table columns are not getting added.

Any luck with the change I posted above?
