Here is the way to disable update check for phpbb3 forum.
1) /adm/style/acp_main.html
Comment out the update check notification red warning box;
Add {# after the <p>{L_ADMIN_INTRO}</p> line and before the {% if S_UPDATE_INCOMPLETE %} line.
And add the #} before the <!– IF S_SEARCH_INDEX_MISSING –> <div class=”errorbox”> line.
2) /includes/acp/acp_main.php
Block by comment out the whole section > acl_get(‘a_board’) as below:
/* if ($auth->acl_get('a_board')) { $version_helper = $phpbb_container->get('version_helper'); try { $recheck = $request->variable('versioncheck_force', false); $updates_available = $version_helper->get_update_on_branch($recheck); $upgrades_available = $version_helper->get_suggested_updates(); if (!empty($upgrades_available)) { $upgrades_available = array_pop($upgrades_available); } $template->assign_vars(array( 'S_VERSION_UP_TO_DATE' => empty($updates_available), 'S_VERSION_UPGRADEABLE' => !empty($upgrades_available), 'S_VERSIONCHECK_FORCE' => (bool) $recheck, 'UPGRADE_INSTRUCTIONS' => !empty($upgrades_available) ? $user->lang('UPGRADE_INSTRUCTIONS', $upgrades_available['current'], $upgrades_available['announcement']) : false, )); } catch (\RuntimeException $e) { $message = call_user_func_array(array($user, 'lang'), array_merge(array($e->getMessage()), $e->get_parameters())); $template->assign_vars(array( 'S_VERSIONCHECK_FAIL' => true, 'VERSIONCHECK_FAIL_REASON' => ($e->getMessage() !== 'VERSIONCHECK_FAIL') ? $message : '', )); } } else { // We set this template var to true, to not display an outdated version notice. $template->assign_var('S_VERSION_UP_TO_DATE', true); } */
Replace the following lins;
<td class=”tabled”>
<strong><a href=”{{ U_VERSIONCHECK }}” {% if S_VERSION_UP_TO_DATE %}style=”color: #228822;” {% elseif not S_VERSIONCHECK_FAIL %}style=”color: #BC2A4D;” {% endif %}title=”{{ lang(‘MORE_INFORMATION’) }}”>{{ BOARD_VERSION }}</a></strong> [ <a href=”{{ U_VERSIONCHECK_FORCE }}”>{{ lang(‘VERSIONCHECK_FORCE_UPDATE’) }}</a> ]
</td>
With the new lines;
<td class=”tabled”>
<strong>{{ BOARD_VERSION }}</strong>
</td>
